third, dont let this shit slide man. Fuck everyone who says take a loss (not really fuck you guys, its all love). But you know where he lives man, this shit ain't over by any means. Go to his parents. Tell them their son is a drug dealer and thought he robbed you off $60 (no need for specifics). Tell them he is ignoring and threatening you. Tell them you are forced to ask them for the money or that you will call the cops and explain to them that drugs are being dealt out of their home. Tell them you are going to tell the cops that you have suspicion that marijuana is being grown in their house. Tell them that an anonymous tip is usually enough for police to acquire a search warrant and destroy their house digging around. I guaranfuckintee you that they will give you the money.
