If you want to learn how to talk to girls, go to the expert: Alec Greven spends his days talking to girls, and has compiled his list of best tips for getting close to a fine young lady into a new book called "How to Talk to Girls". Oh, and the dude is only nine years old. Even at nine, he's got it all figured out: "Pretty girls are like cars that need a lot of oil." Dude, so profound. There's guys in their twenties that haven't figured that out yet. But it just goes to show: not much separates grown-u! p boys and girls from the third-graders.
