YES!!!
When someone looks at you and when you catch them, most people tend to look away quickly. It is more of an embarrassing situation rather than an infatuation. If it occurs often then clearly the both of you are looking at each other too much.
yeah :D
I have actually done this before so i know that if you look at someone and they look at you then you probably do like that person, (if you look at them alot.)
