Unless we're talking about a chance of DD being there during a party, and/or barring any "contraptions" hanging from the ceiling that I would have explain.... what happens in their bedroom (or anywhere else my child is not exposed to) is none of my business.
I'm not saying that I would allow my child to hang out no matter the family situation... but if it was an "approved" friend/family before this tidbit of information, then I wouldn't withdraw all contact/friendship.
Apparently I've got the mind of a 13yo today, because this reply isn't funny, but I giggled the whole time... "hang out" (what's hanging out?), "tidbit" (hopefully things are bigger than a tidbit ), "withdraw"....
