Call me crazy, but...

So there's this guy at work that I think is attractive. It's not like a "wow he's the most amazing creature I've ever seen," but I just find him intriguing. He does have great eyes, but anyway..I could be wrong, but I think he's trying to drop subtle hints to me. It's happened first today. The first time was something about girls, then he looked at me and smiled all irresistible. The second thing I forgot but he looked at me and smiled again.Now, I know that eye contact and smiling are natural occurrences in a social setting, but one can hope lol.
