Need some advice here please. I just bought a watch on CL (I know, I know) about an hour ago. Met in a public place, guy seemed nice enough. Asked him why he was selling it and he said it was his wife's and she didn't want it. Cut to now and I just got an email from him saying "I know this sounds crazy, but can I buy the watch back from you?". This is a first for me. Part of me is wondering what's going on and another part of me wants to just ignore his email because who the hell knows what this could lead to. All he has is my phone number. Meeting place was 20 minutes away and he left before me after the deal was done. Advice?
