I think this was okay to me. The mother was THERE and she was trying to teach her the hard way to get her to learn the lesson. The mother was THERE, and I think it was okay to me, and now the daughter learned her lesson and humilated and she acted out and brought up good grades and everything.
I remember my mother kicked me out the house when I lied to her, and brought home a F in report card on Biology and she threw fit. She told me to get out the house and start looking for place to stay. She said, if I bring my grades up in A and B, she will let me stay home.. If I bring home C, D, or F she will kick me out the house and I have to look for a place of my own. Now I have reached 3.8 GPA in high school and then I went away to college for one year and I had no desire for school, and had a long talk with my mom that I want to work instead of study, so she let me take a break from college and found 3 jobs and making money for myself before I got married (the first one). I would do the same thing with my son when he get in high school. Show the hard way to become a better person with good brain.
