He cannot get angry, it is impossible. He does, however, feel the need to set you in your place when you happen to forget. You are like a dog to him, and he spends a large majority of his time trying to 'break' you, as you would a horse. When you do as he says, he doesn't go without rewarding it, and he simply responds to violence with a smile. When you do something he doesn't like, he tends to say 'so stubborn', and proceeds to punish you as he sees fit.
