Some people like to get up late. Really, really late. As in after noon late. I have never seen him get up before noon unless he has something he MUST go to. And he stays up until four or five in the morning every day. Then whines about how it's dark, all the stores are closed when he's up, and all his friends are asleep or doing homework.
I think he creates his own problems so he has something to whine about. Lucky for me, I can just whine about him.
