The past is haunting me.

An email was just forwarded to me from a mutual "friend" regarding the new contact information for a former roommate of mine. He now lives in Richmond, and his address indicates that he lives really close to me. The problem is this; I am really not sure if I want to contact him or not. We got along fairly well, but I realize that judging from the people he sent his information to, he is still in contact with people that I don't like. At first I thought: "I should totally contact him." After a few minutes I am thiking I should keep my mouth shut and figure that our paths will cross at some point and I will worry about things then.
