Is it weird to message someone you don't really know?

I'm not gonna say guys are pigs, but they kind of are. They'll really only like pictures if they find the person attractive. Or there's the other type of guy who's the cool guy, and if the picture he liked is a picture of you snorkeling or jumping out of an air plane, he might have liked it because he thought it was cool, and thinks your cool. He wouldn't like it if he didn't want you to notice.

I'd say just start out by saying hi. Also it would be best to talk to him in person, but if you don't know where to find him just message him hey on FB, and go from there without being weird. I mean don't tell him something to personal, just keep it to "shooting the breeze chatter". gl
