Was he just being nice?

There's a guy that I have been running into at the Law Office I work at. He works for different firm (on a different floor) but we catch the elevator together often. He would say something funny to me once and a while when we would get on, or laugh at my jokes when I was speaking with another employee the past few times. Today I got the nerve to ask him if he likes his job and what he does. He told me and made eye contact. And then I told him "My name is Krissy by the way." He responded by saying "I'm Aaron, nice to meet you." He smiled briefly, and then I got off and went to my firm, after wishing him a good day.

I feel like I creeped him out!! I can't tell if he was just being nice or if he's attracted to me as well. Please help 😔
