I like Christmas itself but I really hate the the big family get-togethers that happen around that time and all the questions people fire at you relentlessly over lunch, not to mention this one cousin who always asks me why I havn't got a g/f yet every single time and it makes me so angry for the rest of the day. I have to constantly invent things that I have doing apart from my studies when they ask me what i'm up to.
It fills me with dread just thinking about it. Also Christmas equals 40 degree days in Sydney (middle of summer) which equals hell.
The Commercialism of Christmas drives me mad too, but thats another story.
