Something tells you that it wasn't the first time the girl had trouble with someone whose house she parked in front of. It was not her first time doing something silly.
He told his wife she was being silly and not in a funny kind of way when she broke the ceiling fan trying to play basketball in the living room. She told the people at work about her stupid annoying supportive wife always holding her back and how he wasn't being a man about it.
She didn't think it would be silly to shoot her husband over an argument about a garden hose, she thought that he deserved it for being a clown.
