I had a really strange run in a week or two ago, me and a friend went into a place (that my friend really didn't want to go into) but i saw this dude which i had falling out with his best friend/my friend. We did not really talk/hang before the falling out, so we really didn't but i still got invites to his film events last semester. I then thought i saw him at my job yesterday, when i my other friend she said that she thought she saw him eailer at her job (my other job as well). I don't know if we both were not thinking straight, but i swear i saw him. I can't stop thinking about him but is it a good idea to say hi to him and see where it goes? Can this end badly for me?
