So I am a sophomore in college right now and every once in a while, I spot a girl staring at me and I want to know what to do.
Yes, sometimes it could be out of curiousity (im pretty short, although decent/good looking so that could be it) but other times they could find me attractive?
Most of the time when i make eye contact, i will usually look away and keep a neutral expression.

Should i smile and see what happens?
