I finally stumbled on the answer to this question.
In a movie theatre.
A girl will never forget the first boy she ever liked.

Little girl: "Why did you do that?"
Little boy: "Because you smell like dog poo!"
Tears and running to mommy, mommy's response was this little tidbit of pathetic "wisdom":
"Honey, do you know why that little boy did those things? Because he likes you."
That's the beginning of our problem. We are all programmed to believe that if a guy acts like a total jerk, that means he likes you.
I have to go see this movie. It's He's Just Not That Into You With 2 of my girlfriends that went for 19+ years not knowing "does he like me, does he not", falling for the wrong guys (but never dating) only to find ourselves all getting married within a year of eachother.
I've never read the book, but the movie kinda looks cute for girls which kinda watches the misadventures and mistakes of attempting to fall in love =p And not quite succeeding...for some (not so odd) reason.
