This scene is irritating and should be cut
I know a few people have already commented on this, but the part where the ex wife punches her ex husband in the nose. If men aren't entitled to hit women, what makes the woman think she can haul off and hit the man? First of all, the ex husband was not being threatening or calling her names, he was just irritated and surprised to see his ex wife. It's a bad relationship when people hit, regardless of being married or divorced. That scene always bothered me and then for the rest of the movie, his eye look like it really hurt.
"Duh. You're the idiot. Not me."
