New Year's Eve. I never stay up for it. It's so shit. I'd honestly rather be in bed having a snooze, so I do this instead. However the year before last I was rudely awakened by the sound of my cat being shagged on the landing by the biggest Tom I've ever seen. It was literally seconds after the countdown. So she lived it large. And so did he, clearly.
Linked to the above - New Year's Resolutions. 99% of the time they're a sure way to make yourself feel even crappier when the inevitable happens and you ditch them two weeks later, in the middle of January. The coldest, bleakest, most shite time of year and you feel like a FAILURE because you've stuffed yourself full of cream cakes after a fortnight of uncomfortable restraint.
Promotions. Usually a poisoned chalice. For a number of reasons.
Going out for the evening when you're new parents (i.e. the first year after birth.) It's a fucking nightmare getting out the house, you eat/drink really quickly, talk about the baby all night and return home at 9.30am LATEST because you're anxious, only to have the babysitter tell you he/she hasn't woken up at all. And you're over £60 light.
Al fresco dining in the UK. Hate it hate it hate it. Hate the fecking wind in my face, my food going cold in seconds, my hair being fucked up by the elements, feeling chilly. Just want to eat indoors.
Having children. Yeah it's alright sometimes. You love them. But it's hardly roses round the door, they fuck up your house and you have no money. Sometimes they catch you having sex. And they drop your precious things down the loo which really pisses you off.
Having a career is also very shit. Careers aren't nice things, they're bloody horrible. No-body enjoys having a career in reality. Better to have a lower-paid job that you actually enjoy.
