My DH's family hate Christmas, and yet we dutifully drag ourselves over there every other year.
My family: champagne cocktails, beautiful tree, lovely presents, big dinner about 3pm, then turkey and stuffing sandwiches in the evening.
DH's family: never enough roast potatoes, floppy carrots, MIL stressed about the cooking but won't let anyone help (but bitches about it), 'experimental' cake (last year involving vodka: bleuch), crappy presents.
Also, embarassingly, they've decided they like me more than DH, which gets particularly uncomfortable at Christmas. Last year they got me about ten presents, and they got DH one book with really obscenely offensive limericks in it. (I'm no prude, but one of them was about a woman with a smelly c*nt. Nice).
They also give me presents on DH's birthday.
Oh God: only 2 weeks to go.
And I love Christmas...
