My dad's pretty cool with everything that I do. He would let me get a tattoo as soon as im 16. But for some reason he just won't let me get a piercing. On a ear, eyebrow, lip or nose. He's like its disgusting and im like how??? And he just leaves. I've been talkin with him about this for like the past year but he won't give in. Should i just wait till im 18?
