Like many siblings, Malia and Sasha Obama had plenty of times when they didn't get along. During their teen years in particular, the sisters were known to bicker. "When one is 16 and the other one's 13, there's still that sister competition," Barack Obama explained to Hello! in 2020. "'Did you grab my halter top? Where is it? Why haven't you returned it? Why are you doing this, why are you doing that?'"

Despite being residents of the White House, Barack and Michelle Obama endeavored to provide their kids with a normal childhood, including responsibilities like keeping their rooms clean. "People [here] want to make your life easy, and when you have small kids ... they don't need their lives to be easy. They're kids," Michelle told People in 2009.

Even amidst the sibling quarrels, Michelle foresaw her daughters' future closeness. "There was a period of time when they couldn't stand each other, and I said, 'You wait, you are going to wake up one day and you're going to look over at that other person, and you're going to know that you two share something very unique,'" Michelle recalled on "Today." Now the former FLOTUS is happy to see her prediction has come true. "The thing that I love the most is that those two girls are each other's best friends," she added.
