"We are all haunted by the ghosts of our past, but it's up to us whether we let them haunt us or guide us."
Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something, return it better shape (filled up, cleaned) than when you got it.
"I am not interested in the individual fate of the characters, but in the social conditions that produce such fates."
