It doesn't take a Ph.D to know what's important to women -- just ask fourth grader Alec Greven. The 9-year-old has done enough relationship research to literally fill a book.
After seeing boys having trouble around the playground with girls, the young author decided to write a book called "How To Talk To Girls."
Alec told The Early Show's Harry Smith that he pretty much became an expert "just by observing."
His book offers the following useful advice:
Whatever happens, just don't act desperate. Girls don't like desperate boys.
Says Alec, "That's when the girl is just about to ditch you and then the boys get on their knees with their hands together saying, 'please don't' ditch me.' Then she'll probably just ditch you anyway."
Use caution. When you see a pretty girl, don't let her tractor beam pull you in.
"What kind of happens is when you get caught into a tractor beam is the brain turns to mush so you can't really resist it," he explained. Alec says this hasn't happen to him, but he's "seen it happen."
So how does a boy know if a girl really likes him?
Beside a smile, Alec says, "She might share some secrets with you or take you to a secret meeting place. You just pretty much know."
