Jill Biden, the wife of President-elect Joe Biden, has spent a large portion of her life as a politician's wife, but that doesn't mean her life has always been this way. Here are some things you may not know about the next First Lady.

Jill may be the epitome of a refined, well-mannered politician's wife, but she had to undergo a lot of personal development first. In fact, she even described herself as having a rebellious streak in her younger years.

During an interview with The Philadelphia Inquirer, Jill fessed up to sneaking into a popular swim club late at night so as to skip out on the pricey membership fees. She and a close friend opted to scale the fence late at night during the summer and have the pool all to themselves. Jill admitted,

"I can't even believe that I did it."

According to Jill, it was "a long, long time" before she ever told her mother about doing that. She also engaged in other harmless indiscretions, like pulling pranks and sneaking out of school to dine on sandwiches at a local hoagie shop.

As the eldest of five daughters, Jill took on a different role as the fearless protector of her younger siblings. After she had enough of watching her younger sister being bullied, she simply walked up to the perpetrator's door, rang the doorbell, and punched him square in the face. While she may have been in trouble temporarily, she did manage to win her father's praise for that one.
