I might be in the minority here but since it's now December and the other Christmas threads will undoubtedly start, so will I.
First what I do like about Christmas - time off work, bright crisp days. That's it.
What's not to like then?
Enforced 'jollity' - I'll be happy when I'm happy thanks very much not because you're wearing a silly hat and jigging your elbows up and down. Surely the amount of pleasure a human being can derive from blowing a feathery thing from a cracker is limited?
Chaos - nobody knows what day it is, nothing that you would normally rely on can be relied upon e.g. "are the shops open today?" "Are the bins being collected or not?"
At least I can shut out the world and watch xyz on television because it's Tuesday and it's 10 O'clock - WRONG - it's Chrissaamass!!! There's some weird crap on that nobody in their right mind would normally watch otherwise.
Music - As a music lover it's the worst time of year. The handful of good Christmas songs are either played to death (e.g. Fairlytale of New York) or never played e.g. (Father Christmas Eyes). Every single shop, pub, restaurant you go into the same awful crap - you know those horror movies when to depict someone going mad that play a kind of merry go round echoey music? That's me.
Food/drink - Boring. All the same. Especially after the 25th. And it's forced into you - you can't call to anyone without being offered turkey or some bloody weird drink: "have you ever, ever seen me drinking Baileys/Peach Schnapps? So why the hell do you think I'm going to start now?"
Plenty more to grumble about but I'll stop there.
