Easter of course is the end of this week and my family and my boyfriends family are getting together. Problem is his relatives act like they were raised in a barn. I'm very laid back, live in the country but i still have manners and take care of myself. They come over and walk through my flower beds,flick cigarette butts in my yard, we don't smoke by the way, they shovel food slop it everywhere put food back if they didn't finish, food is flying everywhere, they talk about inappropriate things at the table, and when they leave they take half of my kitchen with them. I don't want to be rude, it makes me,my boyfriend and my family highly uncomfortable. What should I do? I don't want to exclude them they don't have anyone else.
