And on Monday, when people ask me how my weekend was, I'll be able to say, 'Actually, I went to the V and A.' No, what I'll say is, 'I caught an exhibition.' That sounds much cooler. (Why do people say they 'caught' an exhibition, by the way? It's not as though all the paintings were thundering past like bulls at Pamplona.) Then they'll say, 'Really? I didn't know you were into art, Rebecca.' And I'll say, smugly, 'Oh yes. I spend most of my free time at museums.' And they'll give me an impressed look and say…

Come to think of it, I've walked straight past the entrance. Silly me. Too busy thinking about the conversation between me and… actually, the person I realize I've pictured in this little scene is Luke Brandon. How weird. Why should that be? Because I table-hopped with him, I suppose. Anyway. Concentrate. Museum.

Quickly I retrace my steps and walk nonchalantly into the entrance hall, trying to look as though I come here all the time. Not like that bunch of Japanese tourists clustering round their guide. Ha! I think proudly, I'm no tourist. This is my heritage. My culture. I pick up a map carelessly as though I don't really need it, and look at a list of talks on things like 'Ceramics of the Yuan and Early Ming Dynasties.' Then, casually, I begin to walk through to the first gallery.

'Excuse me?' A woman at a desk is calling to me. 'Have you paid?'

Have I what? You don't have to pay to get into museums! Oh of course – she's just joking with me. I give a friendly little laugh, and carry on.

'Excuse me!' she says, in a sharper voice, and a bloke in security uniform appears out of nowhere. 'Have you paid for admission?'

'It's free!' I say in surprise.

'I'm afraid not,' she says, and points to a sign behind me. I turn to read it, and nearly keel over in astonishment.

Admission ?5.00.

I feel quite faint with shock. What's happened to the world? They're charging for admission to a museum. This is outrageous. Everyone knows museums are supposed to be free. If you start charging for museums, no-one will ever go! Our cultural heritage will be lost to a whole generation, excluded by a punitive financial barrier. The nation will be dumbed down still further, and civilized society will face the very brink of collapse.

Is that what you want, Tony Blair?

Plus, I don't have ?5. I deliberately came out with no cash except ?2.50 for my curry ingredients. Oh God, this is annoying. I mean, here I am, all ready for some culture. I want to go in and look at… well, whatever's in there – and I can't!

Now all the Japanese tourists are staring at me, as if I'm some sort of criminal. Go away! I think crossly. Go and look at some art.

'We take credit cards,' says the woman. 'VISA, Switch, American Express.'

'Oh,' I say. 'Well…OK.'

'The season ticket is ?15,' she says, as I reach for my purse, 'but it gives you unlimited access for a year.'

Unlimited access for a year! Now wait just a minute. David E. Barton says what you're supposed to do, when you make any purchase, is estimate the 'cost per use', which you get by dividing the price by the number of times you use it. Let's suppose that from now on I come to the V and A once a month. (I should think that's quite realistic.)'If I buy a season ticket, that's only… ?1.25 a visit.

Well, that's a bargain, isn't it? It's actually a very good investment, when you come to think of it.

'OK, I'll have the season ticket,' I say, and hand over my VISA card. Hah! Culture, here I come.

I start off really well. I look at my little map, and peer at each exhibit, and carefully read all the little cards.

Chalice made from silver, Dutch, 16th century

Plaque depicting Holy Trinity. Italian mid-15th century

Blue and white earthenware bowl, early 17th century

That bowl's really nice, I find myself thinking in sudden interest, and wonder how much it is. It looks quite expensive… I'm just peering to see if there's a price tag when I remember where I am. Of course. This isn't a shop. There aren't any prices here.

Which is a bit of a mistake, I think. Because it kind of takes the fun out of it, doesn't it? You wander round, just looking at things, and it all gets a bit boring after a while. Whereas if they put price tags on, you'd be far more interested. In fact, I think all museums should put prices on their exhibits. You'd look at a silver chalice or a marble statue or the Mona Lisa or whatever, and admire it for its beauty and historical importance and everything – and then you'd reach for the price tag and gasp, 'Hey, look how much this one is!' It would really liven things up.

I might write to the Victoria and Albert and suggest this to them. I am a season-ticket holder after all. They should listen to my opinion.

In the meantime, let's move on to the next glass case.

Carved goblet English, mid-15th century

God, I could die for a cup of coffee. How long have I been here? It must be…

Oh. Only fifteen minutes.

When I get to the gallery showing a history of fashion, I become quite rigorous and scholarly. In fact I spend longer there than' anywhere else. But then the dresses and shoes come to an end and it's back to more statues and little fiddly things in cases. I keep looking at my watch, and my feet hurt… and in the end I sink down onto a sofa.

Don't get me wrong, I like museums. I do. And I'm really interested in Korean art. It's just that the floors are really hard, and I'm wearing quite tight boots, and it's hot so I've taken off my jacket but now it keeps slithering around in my arms. And it's weird, but I keep thinking I can hear the sound of a cash till. It must be in my imagination.

I'm sitting blankly, wondering if I can summon the energy to stand up again – when the group of Japanese tourists comes into the gallery, and I feel compelled to get to my feet and pretend I'm looking at something. I peer vaguely at a piece of tapestry, then stride off down a corridor lined with exhibits of old Indian tiles. I'm just thinking that maybe we should get the Fired Earth catalogue and re-tile the bathroom, when I glimpse something through a metal grille and stop dead with shock.

Am I dreaming? Is it a mirage? I can see a cash register, and a queue of people, and a display cabinet with price tags…

Oh my God, I was right! It's a shop! There's a shop, right here in front of me!

Suddenly my steps have more spring in them; my energy has miraculously returned. Following the bleeping sound of the cash register, I hurry round the corner to the shop entrance, and pause on the threshold, telling myself not to raise my hopes; not to be disappointed if it's just bookmarks and tea towels. But it's not. It's bloody fantastic! Why isn't this place better known? There's a whole range of gorgeous jewellery, and loads of really interesting books on art, and there's all this amazing pottery, and greetings cards, and…

Oh. But I'm not supposed to be buying anything today, am I? Damn.

This is awful. What's the point of discovering a new shop and then not being able to buy anything in it? It's not fair. Everyone else is buying stuff, everyone else is having fun. For a while I hover disconsolately beside a display of mugs, watching as an Australian woman buys a pile of books on sculpture. She's chatting away to the sales assistant, and suddenly I hear her say something about Christmas. And then I have a flash of pure genius.

Christmas shopping! I can do all my Christmas shopping here! I know March is a bit early – but why not be organized? And then when Christmas arrives I won't have to go near the horrible Christmas crowds. I can't believe I haven't thought of doing this before. And it's not breaking the rules – because I'd have to buy Christmas presents some time, wouldn't I? All I'm doing is shifting the buying process forward a bit. It makes perfect sense.

And so, about an hour later, I emerge happily with two carrier bags. I've bought a photograph album covered in William Morris print, an old-fashioned wooden jigsaw puzzle, a book of fashion photographs and a fantastic ceramic teapot. God, I love Christmas shopping. I'm not sure what I'll give to who – but the point is, these are all timeless and unique items that would enhance any home. (Or at least the ceramic teapot is, because that's what it said on the little leaflet.) So I reckon I've done really well.

In fact, this morning has been a great success. As I emerge from the exit of the museum, I feel incredibly content and uplifted. It just shows the effect that a morning of pure culture has on the soul. From now on, I decide, I'm going to spend every Saturday morning at a museum.

When I get back home, the second post is on the doormat and there's a square envelope addressed to me in writing I don't recognize. I rip it open as I lug my carrier bags to my room – and then stop in surprise. It's a card from Luke Brandon. How did he get my home address?

Dear Rebecca, it says, It was good to bump into you the other night, and I do hope you had an enjoyable evening. I now realize that I never thanked you for the prompt repayment of my loan. Much appreciated.

With all best wishes – and, of course, deepest sympathy on the loss of your Aunt Ermitrude. (If it's any consolation, I can't imagine that scarf could suit anyone better than you.)

Luke

For a while I stare at it silently. I'm quite taken aback. Gosh, I think cautiously. It's nice of him to write, isn't it? A nice handwritten card like this, just to thank me for my card. I mean he didn't have to; he's not just being polite, is he? You don't have to send a thank-you card to someone just because they repaid your twenty quid.

Or do you? Maybe, these days, you do. Everyone seems to send cards for everything. I haven't got a clue what's done and what's not any more. (I knew I should have read that etiquette book I got in my stocking.) Is this card just a polite thank-you? Or is it something else? And if so… what?

Is he taking the piss?

Oh God, that's it. He knows Aunt Ermintrude doesn't exist. He's just pulling my leg to embarrass me.

But then… would he go to all the trouble of buying a card, writing in it and sending it, just to pull my leg?

Oh, I don't know. Who cares? I don't even like him, anyway.

Having been so ultured all morning, I deserve a bit of a treat in the afternoon, so I buy myself Vogue and a bag of Minstrels, and lie on the sofa for a bit. God, I've missed little treats like this. I haven't read a magazine for… well, it must be a week, except Suze's copy of Harpers and Queen yesterday. And I can't remember the blast time I tasted chocolate.

I haven't read a magazine for… well, it must be a week, except Suze's copy of Harpers and Queen yesterday. And I can't remember the blast time I tasted chocolate.

But I can't spend too long enjoying myself, because I've got to go out and buy the stuff for our homemade curry. So after I've read my horoscope, I close Vogue and get out my new Indian recipe book. I'm quite excited, actually. I've never made curry before.

I've gone off the Tiger prawn recipe because it turns out Tiger prawns are very expensive. So what I'm going to make instead is chicken and mushroom balti. It all looks very cheap and easy, and I just need to write out my shopping list.

When I've finished I'm a bit taken aback. The list is quite a lot longer than I'd thought it would be. I hadn't realized you needed so many spices just to make one curry. I've just looked in the kitchen, and we don't have a balti pan, or a grinder for grinding spices, or a blender for making the aromatic paste. Or a wooden spoon or any scales that work.

Still, never mind. What I'll do is quickly go to Peter Jones and buy all the equipment we need for the kitchen, and then I'll get the food and come back and start cooking. The thing to remember is, we only have to buy all this stuff once – and then we're fully equipped to make delicious curries every night. I'll just have to think of it as an investment.

By the time Suze arrives back from Camden Market that evening, I am dressed in my new stripy apron, grinding up roasted spices in our new grinder.

'Phew!' she says, coming into the kitchen. 'What a stink!'

'It's aromatic spices,' I say a bit crossly, and take a swig of wine. To be honest, this is all a bit more difficult than I'd thought. I'm trying to make something called balti masala mix, which we will be able to keep in a jar and use for months, but all the spices seem to be disappearing into the grinder and refusing to come back out. Where are they going?
