Teenagers should drop non-issues
When I was a teenager, my friends and I would fuss about the fact that we had to keep our hair an inch short at school. Some students preferred taking expulsions and suspensions to cutting off their hair. While there were others who insisted on keeping their nails long and painted and their uniforms short and way above the knees. In my high school, it was against the school rules to wear open shoes or earrings.
Following school rules at high school is positive conduct.
