My theory was that what I had to do was make a study of human behavior.

The crime of suicide lies rather in its disregard for the feelings of those whom we leave behind.

The contradictions are what make human behavior so maddening and yet so fascinating, all at the same time.

It's not what happens to us, but our response to what happens to us that hurts us.

Human behavior is incredibly pliable, plastic.

Entitlement is just the grossest kind of human behavior.
