13 Year Old Nose Piercing?

My 13-year-old daughter asked me if she could get something on her face pierced.  I have no idea where that question came from.  It's the first time she's ever mentioned an interest in any facial piercings.  I told her no to the eyebrow, no to the lip, no to the tongue and "we'll talk about a nose piercing" in a few years so that's what she is begging me to get.  I showed her YouTube videos of nose piercings, thinking it would change her mind, and it didn't work.  It didn't scare her out of wanting it.

I really didn't expect a question like this, but I don't know why.  It just caught me off-guard I guess.  I was expecting questions about the best acne medicine, boys, riding her horse, and the abs on the Twilight guys. I wasn't expecting this.

If I wasn't such a big wimp, I would have a nose piercing.  I actually think a little stud is neat.  I just don't think, at 13 years old, she should be scarring up her nose until she's a little older to make that decision.
