I might have more sympathy here if the brother had suffered extreme loss or if his wife had cheated on him on this day. But, alas, he was the cheating a-hole that caused his divorce. Obviously, he has never had to suffer any sort of consequences for his actions because his coddling parents have kept him from having to take the blame for anything.
This guy is probably better off without any of them around.
For more fun entitled brothers check out this wife's brother who had to be put into his place by her husband because the parents refused to do anything about his behavior.
