I bought my bike when I was 19, and still living at home. My older brother always had bikes, an F2, then F4, and then a ZX-7R. My mom was completely against it, because my dad got cut off by some cracked out chick, and got pretty badly injured, so she tried to change my mind. Never told me no, even though I lived under her roof, because she knew how bad I wanted one, she didn't want it to be a secret. Trust me, she got over the initial fear once she saw me ride, with gear...that's the catch. She felt less stressed about her 19 year old son riding, once she knew I was smart enough to wear gear and be mature on a dangerous machine. The rest is left up to fate. Moral of the story, stay honest and prove you can be trusted to be mature, since you can't gaurantee the drivers around you to be.
