Weird?

Amber

I want a daith or double helix piercing, but my mom won't let me get one. (I'm 16) She thinks I should get a belly button piercing instead but I don't really like those. How can I convince her lol. She had several ear piercings when she was younger, belly button pierced, and two tattoos. (One is a coverup). Also, isn't it weird that she doesn't want my ear pierced but she's cool with my belly button?
