Tea party was nightmare scenario: me plus a roomful of power mothers, one of whom had a four-week-old baby.

'Oh, isn't he sweet?' cooed Sarah de Lisle, then snapped, 'How did he do in his AGPAR?

I don't know what the big deal is about tests for two – this AGPAR is a test they have to do at two minutes. Magda embarrassed herself two years ago by boasting at a dinner party that Harry got ten in his, at which one of the other guests, who happens to be a nurse, pointed out that the AGPAR test only goes up to nine.

Undaunted, however, Magda has started boasting around the nanny circuit that her son is a defecational prodigy, triggering off a round of boast and counter-boast. The toddlers, therefore, dearly at the age when they should be securely swathed in layers of rubberware, were teetering around in little more than Baby Gap G-strings, I hadn't been there ten minutes before there were three turds on the carpet. A superficially humorous but vicious dispute ensued about who had done the turds, following by a tense stripping off of towelling pants, immediately sparking another contest over the size of the boys' genitals and, correspondingly, the husbands'.

'There's nothing you can do, it's a hereditary thing. Cosmo doesn't have a problem in that area, does he?'

Thought head was going to burst with the racket. Eventually made my excuses and drove home, congratulating myself on being single.

Monday 6 March

11 a.m. Office. Completely exhausted. Last night was just lying in nice hot bath with some Geranium essential oil and a vodka and tonic when the doorbell rang. It was my mother, on the doorstep in floods of tears. It took me some time to establish what the matter was as she flopped all over the kitchen, breaking into ever louder outbursts of tears and saying she didn't want to talk about it, until I began to wonder if her self-perpetuating sexual power surge had collapsed like a house of cards, with Dad, Julio and the tax man losing interest simultaneously. But no. She had merely been infected with 'Having It All' syndrome.

'I feel like the grasshopper who sang all summer,' she (the second she sensed I was losing interest in the breakdown) revealed. 'And now it's the winter of my life and I haven't stored up anything of my own.'

I was going to point out that three potential eligible partners gagging for it plus half the house and the pension schemes wasn't exactly nothing, but I bit my tongue.

'1 want a career,' she said. And some horrible mean part of me felt happy and smug because I had a career. Well – a job, anyway. I was a grasshopper collecting a big pile of grass, or flies, or whatever it is grasshoppers eat ready for the winter, even if I didn't have a boyfriend.

Eventually I managed to cheer Mum up by allowing her to go through my wardrobe and criticize all my clothes, then tell me why I should start getting everything from Jaeger and Country Casuals. It worked a treat and eventually she was so much back on form she was actually able to call up Julio and arrange to meet him for a 'nightcap.'

By the time she left it was after ten so I called Tom to report the hideous news that Daniel had not rung all weekend and asked him what he thought about Jude and Sharon's conflicting advice. Tom said I should listen to neither of them, not flirt, not lecture but merely be an aloof, coolly professional ice-queen. Men, he claims, view themselves as permanently on some sort of sexual ladder with all women either above them or below them. If the woman is 'below' (i.e. willing to sleep with him, very keen on him) then in a Groucho Marx kind of way he does not want to be a member of her 'club.' This whole mentality depresses me enormously but Tom said not to be naive and if I really love Daniel and want to win his heart I have to ignore him and be as cold and distant to him as possible. Eventually got to bed at midnight, v. confused, but was woken three times in the night by phone calls from Dad.

'When someone loves you it's like having a blanket all round your heart,' he said, 'and then when it's taken away . . . ' and he burst into tears. He was speaking from the granny flat at the bottom of the Alconburys' garden, where he's staying, as he says hopefully, 'Just till things are sorted out.'

I suddenly realize everything has shifted and now I am looking after my parents instead of them looking after me, which seems unnatural and wrong. Surely I am not that old?

Monday 6 March

8st 12 (v.v.g. – have realized secret of dieting is not weighing oneself).

Can officially confirm that the way to a man s heart these days is not through beauty, food, sex, or alluringness of character, but merely the ability to seem not very interested in him.

Took no notice of Daniel whatsoever all day at work and pretended to be busy (try not to laugh). Message Pending kept flashing but I just kept sighing and tossing my hair about as if I were a very glamorous, important person under a great deal of pressure. By the end of the day I realized, like a school chemistry lab miracle (phosphorus, litmus test or similar), it was working. He kept staring at me and giving me meaningful glances. Eventually

, when Perpetua was out, be walked past my desk, stopped for a moment and murmured, 'Jones, you gorgeous creature. Why are you ignoring me?'

In a rush of joy and affection I was just about to blurt out the whole story of Tom, Jude and Shazzer's conflicting theories, but the heavens were smiling on me and the phone rang. I rolled my eyes apologetically, picked it up, then Perpetua bustled up, knocking a pile of proofs off the desk with her bottom, and bellowed, 'Ah, Daniel. Now . . . ' and swept him away, which was fortunate because the phone call was Tom, who said I had to keep up the ice-queen act and gave me a mantra to repeat when I felt myself weakening. 'Aloof, unavailable ice-queen; Aloof, unavailable ice-queen.'

7 March

9st 4, 2 or 5?? alcohol units 0, cigarettes 20, calories 1500, Instants 6 (poor).

9 a.m. Aargh. How can I have put on 3lb since the middle of the night? I was 9st 4 when I went to bed, 9st 2 at 4 a.m. and 9st 5 when I got up. I can understand weight coming off – it could have evaporated or passed out of the body into the toilet – but how could it be put on? Could food react chemically with other food, double its density and volume, and solidify into every heavier and denser hard fat? I don't look fatter. I can fasten the button, though not, alas, the zipper on my '89 jeans. So maybe my whole body is getting smaller but denser. The whole thing smacks of female body-builders and makes me feel strangely sick. Call up Jude to complain about diet failure, who says write down everything you've eaten, honestly, and see if you stuck to the diet. Here is list.

Breakfast: hot-cross bun (Scarsdale Diet – slight variation on specified piece of wholemeal toast); Mars Bar (Scarsdale Diet – slight variation on specified half grapefruit)

Snack: two bananas, two pears (switched to F-plan as starving and cannot face Scarsdale carrot snacks). Carton orange juice (Anti-Cellulite Raw-Food Diet)

Lunch: jacket potato (Scarsdale Vegetarian Diet) and hummus (Hay Diet – fine with jacket spuds as all starch, and breakfast and snack were all alkaline-forming with exception of hot-cross bun and Mars: minor aberration)

Dinner: four glasses of wine, fish and chips (Scarsdale Diet and also Hay Diet – protein forming); portion tiramisu; peppermint Aero (pissed)

I realize it has become too easy to find a diet to fit in with whatever you happen to feel like eating and that diets are not there to be pick and mixed but picked and stuck to, which is exactly what I shall begin to do once I've eaten this chocolate croissant.
