So fairly straight forward. Never really had this happen to me much but I saw it happen the other night and wondered what I'd do in the same situation. It made the dude look pretty uncorfatable and he didn't really know what to do with himself. Seemed to me like this other dude was an old friend or maybe BF, and they talked for a good while. Do you look so as you're completely disinterested? Or do you step in? Or leave? What would be the best course of action here?
