see i'm mixed on all of this. i am 24, and when i was 18 i handled responsibility better then alot of people did my age. I had a full time job, was never late, paid my bills on time, never got in trouble, had a knowledge of right and wrong, stayed out of trouble, and all around responsible. is that what makes someone a adult? i dont know what each persons idea of adult hood it. But i do know that there were people that i knew at that age that werent responsible enough (at the time) to manage there finances, were doing stupid stuff, or just thought they were better then everyone else. Those people i never trusted. There were some that were responsible that i would have trusted to carry (at that age). How ever those people were far and few in between.
i dont want to take anyones liberties away from them (except criminals and the inept) but i think the system is good where its at.
