Why would he let me know he was checking me out?
The other day, my co-worker, who I'm getting to know (on a friend basis) called my name and then looked down and then up at time (like he was checking me out) and nodded. And I was like, "what??" (in my head). I have caught myself kind of flirting with him, but not intentionally, and I like having conversations with him and we get along and I think he's a great person.
Did he do this because he likes me or that he likes something more? I was just totally caught off guard and now I can't stop thinking about it.
