My parents can be pretty laissez faire/let us do our own stuff in some ways. I've been using the internet and playing games without much parental supervision since I was in elementary school. But it's not like I do anything illegal or inappropriate...
And yet in other ways they can be pretty...not. I'm going to hang out with someone they don't know? "I don't know, you need to tell us everything about them and what time you'll be home, what you're doing, etc..." ^^' Most of the time it's not too bad I guess, and even though I'm 18+ I still live under their roof so they've got rules too.
