what Rat said is once again agreed with.
my group of friends probably fits into that "rough looking kids" category.
Example:
were just like everyone else, man. we hang with everyone from preps to rednecks. so next time, just chill out and like you would anyother time and take it easy. no ones going to hate you unless your a rude asshole.
but yeah, you've totally blown your first impression. can you redeem yourself? sure, why couldnt you? just hang out with her and give it some more time.
good luck, buddy.
