Part of the problem with the educational system is that the teachers want to be too friendly with the students.
When I was in school, I got along with most all of my teachers, but there was a line. They took an authoritative position and we all respected it. They were there to teach and we were there to learn. Now days teachers want to molly-coddle the kids and be buddy-buddy with all of them and to heck with the 'teaching' part.
