Spenser: Wow. That's really nice of you but, I've always thought of you as a friend. It's not that I don't like you; I just don't like you in the same way that you like me. I am really sorry that we don't share the same feelings for each ohter; the last thing that I would want to do is upset you. Could it be enough if we were just friends? You are cool anf funny so I hope that this won't make it weird between us. There are still a lot of people who you could get to know and like more than me. I would like to complimate you for having the guts to tell me this. I have never told someone that I like them before. Once again, I am really sorry and I hope that we can still be friends.

Allen: You cruel, heartless monster.
