I have this friend, my husband and I have known her and her husband for about 2 years. Our daughter went on a camping trip with their daughter and when she got home today she said that they argued the entire time. Not just a verbal argument, but her husband threw a drink at her and they screamed and yelled 3 out of 4 nights. We did not know this side of their relationship, and I'm very upset. I don't know what to say to her, obviously my daughter is not going back over there, but it just makes me cringe to hear her talking about the insanity that went on...So I am not sure if I should confront this couple or just let this be a lesson learned and keep my mouth shut?
