During a visit to Georgia, Obama hinted that one of his daughters -- likely oldest teen Malia -- was already having boys knock on the door of 1600 Pennsylvania Avenue. "I do have to warn the parents who are here, who still have young kids, they grow up to be, like, five feet 10 inches. And even if they're still nice to you, they basically don't have a lot of time for you during the weekends," he said. "They have sleepovers and dates. So all that early investment just leaves them to go away."
