Most Helpful Guy
Honestly, that might have some truth to it. I myself virtually can never tell if a woman is interested in me, and most guys really can't either, they just assume that the woman is and playing hard to get, or they are so deluded with themselves, they really do think everyone loves them.
If that is true however, I would like to make one similar observation. Although women might be better in telling who is into them, given how many times women have gone with guys that most other guys including myself know full well don't care about them at all, and are just using them for sex, I don't think they are very good at knowing WHY a guy is interested in them.
