also-- professors have respect for their students-- they treat their students as adults who are there to learn. They're not there to babysit you-- you are free to leave, and they are not responsible for you or your actions. In high school the teachers don't have respect for their students (not that they should)--they nag, babysit, and micromanage. In return students don't have respect for their teachers, and there is an "us" vs. "them" attitude that leads to misbehavior. In college you sometimes become friends with your professors, or in the least there is cordiality. Additionally, college students are older, and therefore more grown-up, and act accordingly.
also-- when you're in high school you're "required" to be there-- when you resist there are a million people there to catch you when you call-- counselors, teachers, faculty, parents, etc. that are there to help you when you misbehave to get back on the right track. When you're in college, no one gives a fuck if you fail or succeed. At that point your success is up to you and they wont hesitate to drop you for bad grades, or kick you out for doing something inappropriate.
