Yeah, I'm a chronic smiler. And I happily chat with everyone I meet, like a little kid would.

Nobody seems to interpret it as flirting, although I'm so spergy that I can't really tell if someone finds me attractive, unless they're extremely obvious about it. And then it's too late to clarify.

I guess that's why I am under the impression that I'm not that attractive, but men occasionally suddenly lose their minds and get sex-rabies around me. There was probably a whole phase in-between, that I completely missed.

The concept that men are often thinking about sex and masking it, helps explain the sex-rabies thing.
