What does it mean if a guy tucks a girl's hair behind her ear?

Anonymous
I was just curious if this is just a friendly gesture or if it can have other meanings. I was hanging out with my guy friend and all of a sudden he reached over and moved my hair behind my ear. It seemed a little strange because I wouldn't say my hair was really blocking my face too much and he could have just said something. I guess he was being nice.
