Kvod Harav
Is it considered that I'm an accomplice in my OTD sister's sins if I drive her (and her friends) someplace? Not specifically to a forbidden place. Whether they will chill together somewhere, go to a mall (they may buy immodest clothes, eat non kosher...) etc? Also, I think you said something recently about how we can't drink wine that someone who is mechallel shabbat poured. Does that apply to her (she is mechallel shabbat)? Can I not drink from the bottle once she pours from it? And are there any related issues that I need to be aware of when living with someone like this?
