Why would a guy act like this after following him on Facebook?

I truthfully was not aware that I pressed anything.. he’s cool and I know his family. He lives in a different state and him and his wife came to town.

Now I didn’t realize I was following him for weeks! I know I must of did something when I waved and he didn’t say nothing or wave back. Like every time I tried to speak or be friendly he was just weird. So I checked to see if I accidentally liked something and it said we are “friends”…

but if he felt some type of way he didn’t have to “accept” it etc..

I immediately unfollowed.

im not too familiar with him
