Your parents are responsible for providing the necessities of life, giving you a roof over your head, feeding you and providing an environment conducive to learning and growing into a well balanced adult.
Automobiles and college educations are not necessities - no matter what the TV ads or other kids say.
Get a job. Take night classes. Eat Top Ramen. Buy the cheapest toilet paper. Scrimp, and save. Build your own empire. One that nobody but YOU can lay claim to.
As an old song says:
Momma may have and Papa may have, but God bless the child that's got their own...

and maybe one day, you'll know who is buried in Grant's Tomb
