Liking a guy twice your age?

Anonymous
This may sound gross to some of you, but there's this guy which I presume is twice my age (I'm 18) in my campus. Aaand he's a teacher, tho he doesn't teach me. But he's not the serious teacher type, he sometimes comes to my class and goof around. Its not that I'm 100% sure that I have a crush on him, but the first time I saw him was before I went to that college and I was only there for a short course. I was like staring at him for some unknown reason until he realizes and stares back. And after that whenever he sees me or vice versa we sorta look at each other for a few sec until now. I don't know if he knows my name tho. Last month our campus held a party in a club and he was like acting all crazy, we were on the dancefloor and exchanged look but didn't get to dance together cause it'll be awkward for sure. And now I'm starting to find myself looking around for him in a way someone would look around to see if his/her crush was around. I even thought of saying hi or at least smile when I see him(he usually only give this stern look).What am I actually feeling/thinking?
