I'll also say...keep at it. let em know how much it means to you. I was a drummer since 4 years old...my parents didn't want me to have a bike. I worked on them for several years till they caved in. Only problem was, I needed a new set of drums as well. They said drums or dirtbike. Had to have drums. Point is, over time they realized how bad I wanted a bike and finally were cool with it. I didn't get a bike till I was 25....and it was worth ALL of the wait.
