When I pass my crush from my course, he will avoid eye contact whilst greeting me. He turns his head around to look at something else whilst talking so I can't see his face or looks behind him instead of looking at me and will avoid holding eye contact for more than a split second.
We get along well, help each other with coursework and have known each other almost a year, so I don't know why he would feel awkward. He is nice to me and not shy or awkward around people or bad at eye contact in general (he's confident and a social butterfly) so why would he do this?
