My family are going for Christmas at my sister’s house and she’s just said she wants £30 for us to attend! It’s not like I show up empty handed, I always bring a bottle of wine and some crackers for the cheeseboard. It’s put a bad taste on my mouth and I’m tempted to tell her to sod the charge and we’ll spend Christmas at home, but then the children will miss out on Christmas with all their cousins and grandparents. IABU to think charging family for their Christmas dinner is wrong?
