'How did you know that?'

'Word on the street. Andrew called Rupes this morning about cricket, and he told him.'

'Are you moving in with Connor?' says Lissy incredulously. 'Why didn't you tell me?'

'I was about to, honestly. Isn't it great?'

'Bad move, Emma.' Jemima shakes her head. 'Very bad tactics.'

'Tactics?' says Lissy, rolling her eyes. 'Tactics? Jemima, they're having a relationship, not playing chess!'

'A relationship is a game of chess,' retorts Jemima, brushing mascara onto her lashes. 'Mummy says you always have to look ahead. You have to plan strategically. If you make the wrong move, you've had it.'

'That's rubbish!' says Lissy defiantly. 'A relationship is about like minds. It's about soulmates finding each other.'

'Soulmates!' says Jemima dismissively, and looks at me. 'Just remember, Emma, if you want a rock on your finger, don't move in with Connor.'

Her eyes give a swift, Pavlovian glance to the photograph on the mantelpiece of her meeting Prince William at a charity polo match.

'Still holding out for Royalty?' says Lissy. 'How much younger is he than you, again, Jemima?'

'Don't be stupid!' she snaps, colour tinging her cheeks. 'You're so immature sometimes, Lissy.'

'Anyway, I don't want a rock on my finger,' I retort.

Jemima raises her perfectly arched eyebrows as though to say, 'you poor, ignorant fool', and picks up her bag.

'Oh,' she suddenly adds, her eyes narrowing. 'Has either of you borrowed my Joseph jumper?'

There's a tiny beat of silence.

'No,' I say innocently.

'I don't even know which one it is,' says Lissy, with a shrug.

I can't look at Lissy. I'm sure I saw her wearing it the other night.

Jemima's blue eyes are running over me and Lissy like some kind of radar scanners.

'Because I have very slender arms,' she says warningly, 'and I really don't want the sleeves stretched. And don't think I won't notice, because I will. Ciao.'

The minute she's gone Lissy and I look at each other.

'Shit,' says Lissy. 'I think I left it at work. Oh well, I'll pick it up on Monday.' She shrugs and goes back to reading the magazine.

OK. So the truth is, we do both occasionally borrow Jemima's clothes. Without asking. But in our defence, she has so many, she hardly ever notices. Plus according to Lissy, it's a basic human right that flatmates should be able to borrow each others' clothes. She says it's practically part of the unwritten British constitution.

'And anyway,' adds Lissy, 'she owes it to me for writing her that letter to the council about all her parking tickets. You know, she never even said thank you.' She looks up from an article on Nicole Kidman. 'So what are you doing later on? D'you want to see a film?'

'I can't,' I say reluctantly. 'I've got my mum's birthday lunch.'

'Oh yes, of course.' She pulls a sympathetic face. 'Good luck. I hope it's OK.'

Lissy is the only person in the world who has any idea how I feel about visiting home. And even she doesn't know it all.

FOUR

But as I sit on the train down, I'm resolved that this time will be better. I was watching a Cindy Blaine show the other day, all about reuniting long-lost daughters with their mothers, and it was so moving I soon had tears running down my face. At the end, Cindy gave this little homily about how it's far too easy to take our families for granted and that they gave us life and we should cherish them. And suddenly I felt really chastened.

So these are my resolutions for today:

I will not:

Let my family stress me out.

Feel jealous of Kerry, or let Nev wind me up.

Look at my watch, wondering how soon I can leave.

I will:

Stay serene and loving and remember that we are all sacred links in the eternal circle of life.

(I got that from Cindy Blaine, too.)

Mum and Dad used to live in Twickenham, which is where I grew up. But now they've moved out of London to a village in Hampshire. I arrive at their house just after twelve, to find Mum in the kitchen with my cousin Kerry. She and her husband Nev have moved out too, to a village about five minutes' drive from Mum and Dad, so they see each other all the time.

I feel a familiar pang as I see them, standing side by side by the stove. They look more like mother and daughter than aunt and niece. They've both got the same feather-cut hair — although Kerry's is highlighted more strongly than Mum's — they're both wearing brightly coloured tops which show a lot of tanned cleavage, and they're both laughing. On the counter, I notice a bottle of white wine already half gone.

'Happy birthday!' I say, hugging Mum. As I glimpse a wrapped parcel on the kitchen table, I feel a little thrill of anticipation. I have got Mum the best birthday present. I can't wait to give it to her!

'Hiya!' says Kerry, turning round in her apron. Her blue eyes are heavily made-up, and round her neck she's wearing a diamond cross which I haven't seen before. Every time I see Kerry she has a new piece of jewellery. 'Great to see you, Emma! We don't see enough of you. Do we, Aunty Rachel?'
