Why do most people change when they get to high school?

    Many students change when they get to high school beacuse they want to make a good impression about themselves. Most students want to have a new begining, new friends, and better grades.There are also some students who completely change ignoring there old friends,they think they are better than everyone else when they get to high school. I guess most people think high school is the place for change, where they can do whatever they want. The teachers in high school dont care about the students,if they are failing and not attending classes.Not to mention, high school is a place where students change and do whatever they want.
