Well, I did some pretty wild stuff when I was 23 - but my dad wasn't President. I am sure she regrets it now - but I am not gonna beat up on her.
At 23, she has to know that she's under a microscope. I can't imagine how tough it would be to be in her shoes, but she's old enough to know that she'll have to pay the consequences for her actions...and so will her parents.
I'm glad my dad was never the President: I'd have been a problem for him.
