One of my sisters was drugged out one night and my mom confronted her about it. They argued, and my sis slapped my mom, and my mom had her pack her bags and threw her out of the house that night. I think my sis was 17 at the time, might have been 18. Life got kinda hard for my sis after that: no job, no college money, no place to live. I suspect she ended up regretting slapping my mom.

You take some big risks when you're 17+ and you start disrespecting your parents, because they don't HAVE to pay for your food and utilities and a roof over your head and clothes and school and whatnot. I know if I had a child that disrespected me in my own house, who was that age, I'd boot him or her out too, let 'em see what life on the street is like for a while.
