Don't ever expect a human to be anything other than a human. No man is immune from ANY human behavior. Though they may be self-aware, introspective, deep, yada yada....he's still a human.

No man is infallible either.

There is a movie segment that I would LOVE for you to see. Title: Bead Bang, staring Don Johnson.

The set-up is that he's a failing cop and was sent to a T for evaluation. Don (Mr Beck) trusted and expected the T to be above the human reacation scales.
