Slowly, please.
Actresses Mary-Kate and Ashley Olsen are twins. Although the twins are very similar, they aren't identical. Mary Kate is shorter than Ashley and the sisters write with different hands.
The twins'careers began as babies, when their parents took them to an audition for a TV show called Full House. Mary-Kate and Ashley got the job because they didn't cry at the audition. The girls grew up in front of the camera. They learned to walk and ride a bike while they were doing the show.
