SIL asked what we were up to this weekend. I said, as another storm is on the way, we were going to have some mulled wine and a cheeseboard while watching Christmas films. She then did cat's bum face and said she thought it was so gross that people do nothing but stuff their faces with unhealthy food in the run up to Christmas. She said this, by the way, in front of her teenage daughter who has struggled badly with body image issues. I said, lightly, that I'm very sleep deprived due to my velcro 5 month old and, as last Christmas (and for the whole 9 months of my pregnancy) I had hyperemesis gravidarum and was too queasy to enjoy any nice food, this Christmas I fully intend to eat all the cheese and all the chocolate. She rolled her eyes at me and said "whatever makes you feel better about yourself".
I said nothing but I wanted to tell her to fuck off tbh. AIBU?
