Sometimes yea, it usually depends on the people and situation.
However, if it happens on more than one occasion, like for example, you and a guy lock eyes a couple of times every time you both are near each other in the library or something, THEN I would consider that mutual attraction.
ye seems like you are both curious to know one another as in what would it be like to know each other...so yes there is a connection..but I normally prefer to speak and see who that person is to find out thier intentions. but again its up to you how you handle it :)
personally, when I like someone I keep eyecontact DURING conversation. If not, I'll just give them a death stare lol
