he smiled at me every time our eyes met...but I didn't smile back cause he was using computer...so maybe he was smiling for other reason

Maybe he's having a good day, or he thinks you're cute, or he's just feeling chipper. The possibilities are endless.

It could mean anything :P Maybe he's just friendly.

he had just heard a funny joke and thought of it, it is only a coincidence that you two looked at each other

[hALLDAY]

It could mean a bunch of things.

usually they are physically attracted to you
