Replying to I'm an idiot

the one day i ask my parents to let me use their vehicle to drive to school all damn year i hit a car pulling into a parking spot.it was to small of a spot for me to fit and i ended up scratching the front of their car and my side door. I'm so fucked, haven't told them yet..cops came and aren't filling out an accident report because the damage is minamil, however i'm gonna pay alot to have it fixed, like prob anywhere from $500-$1,000. ahhhhhhhhh!
