This is "old fashioned" but it works. When my brother and I were going to school my Father told us even a moran can sit there and keep it's mouth shut. If we got into trouble at school we got it worse when we got home. I taught my 3 children the same way and I taught them their job was to go to school for an education and not socializing. All 3 of mine graduated high school. One went to college, one to technical school, the other is still finding herself lol but she graduated high school and is working full time.
