"Don’t you ever believe that what we did was in vain, son. Never think that. That poor lady would have died alone on that bench if we hadn’t stopped. As it is, you kept her company and there were people with her when she went. So it wasn’t in vain. Nothing is in vain. Always, always remember that. Everything matters."
