A couple of months ago, LC and her friends showed me a video that another one of their friends posted on Facebook. This kid (14 at the time) was recording herself, and her mom (who I've known for years) comes in the room and says real casually, "Hey genius: your pot smoke is going right in my bedroom window."
The kid then looks surprised and turns off the camera. I couldn't believe it. I've known this kid since she was born, and the mother longer than that. The mom didn't sound surprised, alarmed, nothing.
