It really sucks. We usually go to the in-laws with all of the cousins, but there's a civil war going on between my wife's siblings. Sister 1 can't be with sisters 3 and 4. Sister 3 can't be around her mother. Sister 2 can't be around her mother or brother. It's just ridiculousness. Everything from politics, to religion, to arguments from 5 plus years ago. None of them can stand to be around each other, and now all of the young cousins have to suffer.
