Seriously, get off your high horse. You don't need a car. Stop making up excuses on top of excuses. Talk to your friends in school. REAL friends will understand. Everyone else will be an ass, you'll get over it, go to college and never see them again.
You don't need to go to a mall to hang out and waste MORE of your parents money to buy crap you won't use in 3 months and will clutter you doubtless oversized house.
The more excuses you pile on top of excuses, the more you sound like a whiny, sheep-minded brat. "It's uncool" to hang out at a park? "Everybody else has a car?" "Nobody skateboards or skates?" "Little kids do that?" Seriously, it sounds like you just wanna be everyone else. Use your brain, do something different, HAVE A MIND OF YOUR OWN. Stop being so materialistic and simple minded.
By the way, no one cares about your excuses and why you supposedly NEED this car to fulfill your childish desires. Apparently you're so rich you've never had to think out of the box.
A need is something you have to have, something you can't do without. A good example is food. If you don't eat, you won't survive for long. Many people have gone days without eating, but they eventually ate a lot of food. You might not need a whole lot of food, but you do need to eat.
A want is something you would like to have. It is not absolutely necessary, but it would be a good thing to have. A good example is a car. Now, some people might argue that a car is a need because they think they can't do without it. But you don't need a car to survive. You do need to eat.
Are you SURE you need a car? I doubt you'll die without one.
