How old are you? Just wondering how long until you're 18 and can do (in theory) whatever you want!

Maybe buy some new clothes, paint your nails black, or do something else different yet not permanent that gives you a feeling of change. Style your hair differently without cutting it. Maybe go in for a trim, and have the stylist "accidentally" take off too much... What about temporary hair color?

Honestly, I can understand her not wanting you to get piercings, but hair color? Unless you want to dye your hair blue or something, I don't see what her problem could be. Maybe just talk her into one small change at a time - can I take 2 inches off my hair? Can I get a cartilage piercing? One thing at a time! Be persistent. She probably is just afraid you want to do these things now and will regret them in a week. Keep asking and begging (be nice about it! ) and I bet she gives in to at least one thing soon!

Good luck!
