I was once approached by a man who claimed to have seen both heaven and hell. Out of curiosity, I decided to hear him out. "Heaven and Hell aren't that different", he explain. "What do you mean?", I asked He took a short pause. Perhaps, I was imagining it, but I swear I could see sadness in his eyes. "Hell is when you relive your worst nightmares over and over again", he said. "Hell, is when you know bad things are going to happen, but you will always be too powerless to stop it."
