Even if that happens it will eventually go away

Buddy, I reckon your thinking too much about this too early in your life. Right now you shouldn't worry about these kind of things. You'll find that as life goes on you'll find the right time to bring it up, but now is not the time.

It's good to have a dream, but hey.

yeah, learn to drive, drink (note: do these separately!!) and how to party (dancing goes down very well with the ladies)
but yeah, once ur 18, ur legally an adult and there is nothing they can do to stop you

If you are really worried about what your parents think and you really want to convince them, then I think they did a good job raising you. When you turn 18, I think you will have what it takes to make the right decision for yourself and pursue your dreams.
