To Mom’s of teens: I need opinions

My 17 year old daughter just graduated from high school. Yesterday she was at her bf’s house for his graduation party and apparently his parents allowed them to drink. My 17 year old daughter was drunk as a damn skunk last night! I can handle my daughter on this but I am no longer comfortable with my daughter spending time over there. She’s grounded now but she won’t be grounded forever and I’m sure she’s going to want to go back over there. I’ve spoken to his Mom before and they’re self-proclaimed “hippies” over there and allow their kids more “freedom”…..I see it as a lack of boundaries.

My daughter has a 4.4 GPA, graduated with high honors, has a full ride scholarship to MIZZOU, and she was raised with boundaries. This is the text I got from her….

I’m going to speak with his parents to get their take on what happened but what would you do?
