So. I thought FMIL was out of hand, I guess I was wrong.
Here's the story...I am only having 3 children at my wedding, those part of the wedding party. One flower girl is my niece (Flower Girl A), my sister mentioned that she was going to bring a separate dinner because (FG A) is a picky eater (doesn't want her to just eat dessert) I think, oh that's a good idea! She doesn't like a lot of food and will want to fill up on sweets, this way if there's a food battle with whats on the menu then my sister has a back up meal. Other flower girl is FI's cousin's daughter (Flower Girl B ). I contact FI's cousin "Hey, my sister is bringing an extra dinner for (FG A) because she is a picky eater. I was wondering if you think (FG B ) will like the food on the menu for dinner or if you wanted to do the same. Convo continues...Menu is salmon, filet mignon and chicken parmesan. I explicitly say word for word "I know the kids will enjoy the appetizers and desserts. I was just wondering about dinner" no response.
Cousin calls her dad, who calls his bother, who then calls FMIL..."Did you say that (FG B ) won't be allowed to eat at the wedding?! *Face Palm*
Looking back, I could have worded it better. Or maybe I should have never mentioned it at all. I'm guessing the latter. I'm just astounded that there was a game of telephone that went terribly wrong and now the family is "up in arms"
