Last advice, if her mom looks really upset or angry, remind her that her daughter is a good kid, a good worker, and smart. She just made a mistake. I'm the oldest and so my parents went through all my shit for the first time. My friend had 3 older brothers so her parents were already experienced in the teenage ways. My parents would get really wrapped up and act like a nug of weed was the the end of the world. They started crying when they found out about the party. My friends parents reminded them that of my group of friends I was the most responsible and that I put school and work first unlike their daughter and it opened their eyes to the bigger picture. Sometimes parents can forget that their kid is actually a good kid when they fuck up.
