This conversation is bound to turn up. Two guys in a street meet each other, and one of them says, "Hey, did you hear? Phil Davis died." "Phil Davis? I just saw him yesterday." "Yeah? ... Didn't help. He died anyway. Apparently, the simple act of you seeing him did not slow his cancer down. In fact, it may have made it more aggressive. You know, you could be the cause for Phil's death. How do you live with yourself?"
