Little is known of Harley Quinn's life before she went to Arkham Asylum as an intern.
We can speculate that, as an attractive, athletic and ebullient person, she was a highly popular young woman, growing up with lots of friends and enjoying a stress-free life. Maybe she was part of her high-school's cheerleading squad. She was almost certainly on the gymnastics team.
