We will be having:
the 'if you don't make your special stuffing in time for it to be cooked with the meal then I will be using PAXO' one
the 'if you prefer to complain about the commercialisation of christmas rather than say thank you for a present then I won't bother getting you one next year'
My mother's favourite 'no one else bothers doing anything round here you're all ungreatful brats'
The 'who forgot to set the video' one (this is especially good in the middle of dinner)
Everybody's favourite 'you're all horrible and I'm not eating with you'
and the 'completely unrelated subject that could have waited till boxing day' one.
What are your traditional family fights?
