I'm 16, a month away from 17, and there's a boy my dad says I can't be alone with. He has let me be alone with boys he has never even met before but he won't let me be alone with this one. We always hung out but one day my dad says no. If I hung out alone with this guy (he's the same age) and my dad called the cops (which he would), would I get in trouble with the police for hanging out with someone my dad doesn't want me to? Can he say who I can and can't hang out with? By the way this boy is not bad but he is black and alot of the time i feel my dad is racist. When i move out i will most likely be estranged from him. Also my mom lets me hang out with him alone, she doesn't pick my friends. This guy is not my boyfriend and I don't want to go out with him. We are pretty much best friends. So my basic question is, Can I hang out with this guy when my dad says no, or will i get in trouble with the police? (I'm 16 going on 17)

i found a peice of amethyst about the size of a crumpled up piece of paper. In some spots it is a dark and pretty purple. How much would it be worth?
