For me - family pyjama pictures - you know the ones where mum, dad, child & baby wear the same PJs - you all look like pillocks and/or like you're part of a cult. - mummy martyrs. Women (and sorry it is women and yes I know theres bigger expectations around them at Christmas) clanging pans around the kitchen from 7am - 6pm on Christmas Day, making far too much food that nobody especially asked for, refusing to let anyone help but complaining you're doing it all on your own. Just STFU and order a takeaway if you're gonna have a nervous breakdown over sprouts. - most Christmas specials (except the first Gavin and Stacey one where Nessa have everyone a celebration chocolate [fgrin]) - although I do have high hopes for the Motherland Christmas Special!
