I was standing there talking to an old friend. Then the guy I used to see was walking up (I didn’t see if he looked but he was walking towards us) I ended the conversation. As soon as he walks off my guy sits down next to a couple girls being obnoxiously loud chatting. I just got back to work laughing & joking with my co worker. She said he peaked in (his brother was there) glanced at me & walked away. Am I overthinking? We don’t talk anymore but it’s always tension or awkward. Is something still there?
