Don't Hit Me; I'm Too Smart!

I am playing with a cockatiel. It is very smart. I hit it on the back of it's head. It jumps off its perch and marches away crying. I follow it. It turns around and yells "Don't Hit Me! I'm Too Smart!" I tell it I'm sorry, and I am. The bird then climbs on my finger and snuggles against me shivering like it's just desperate to be loved. I pet it and feel guilty. Even after I wake up I feel guilty all day.
