Oh that's an easy one.
My brother tries to bring up a fight with me everyday just because he's angry and he "needs to let it out".
For what reasons?
A dvd is missing. A memory card (ps2) is missing. He hit his toe. He didn't get his breakfast in time. His friend misunderstood him. He misunderstood a friend. He can't find a certain shirt. He can't find a pen. He can't find a pencil. He doesn't like how something looks like. He forgot what he was looking for. He can't remember where he put something. I won't do what he wants me to do (he could do it himself... he's more capable, too. I ain't a slave. ) when it's somethign HE should do. His cellphone won't get reception. It's raining on a day he wanted to go out. etc etc
basically, if anything doesn't go SPECIFICALLY his way... he gets pissed.
O_O *ahem* Excuse me for my informal expressions!
