he has no patience

He's heading towards his xbox to play a game and asks me to hand him his ipad, so he can listen to his favorite radio station through the internet. The first thing I hand him is the case of sodas he had next to the couch so he would have something to drink while he's in there. In a very irritated tone, "No, I said ipad." I told him to chill, I was going to get his ipad next. He has no patience.
