When me and this guy I work with walk by each other, he would look down when we make eye contact, but then immediately look back up and hold it as we pass each other. Like just looking straight in my eyes and we don’t look away. Honestly, I think it’s kind of hot. But I’m not too sure if this is a sign of interest. Other times in crowds, he’d see me and we’d hold eye contact in passing but I do not see him very often. I’m not too sure what to make of these exchanges(if there even is something going on). He doesn’t smile or anything. I just don’t want to go up to him and make a move without proper information and make myself look foolish. We are both guys(but I am Black and he is White? Latino).
