Can a boy and a girl share the same room?

I have this friend and she has one bedroom and she shares it with her younger sister and her older brother and he's 18. I mean is that illegal or something???

No. That just means they're poor and they don't have the money for a bigger house. It isn't illegal. The only thing that would be illegal is if he started dating her or molesting her.

No, there's nothing illegal about it. There used to be cohabitation laws in in United States that said an unmarried man and a woman couldn't share the same domicile, but those are now largely ignored, and besides, they never applied to siblings.

haha no , thats her brother . the only way it would be illegal is if he was doing something to them, or if it wasn't her family.

its legal they are siblings

its not illegal , as long if he doesnt molest them or anythin its fine

Hello there brother and sister's?
how can it be illegal?
