Maybe because you're cute? I laugh at guys I think are cute...
They think I'm cute or something like that. I try to react the same way even if I don't mean it.
Have an opinion?
I had one guy laugh at me once.Just looked me up and down and gave me a single: "Heh."So I did the same and flipped him off.
No, I'm not paranoid.
they shame me
Depends on the context, it could be just being friendly
