when did education become a burden?

I am not sure what you consider "fun". When I started school, it was - but until I hit high school , I had various teachers who seemed to like to pick on me for some ungodly reason. With the exception of raising my hand in class to answer a teacher's question during a lesson, or ask a question, I kept to myself and behaved as I should do and my parents instructed me. But I had a fifth grade teacher who wrote down everytime you "spoke out of turn" - and she wrote me up when the person in back of me poked me in my back and whispered something I didn't catch; all I did was turn and say, "What?" She didn't catch the kid who did the whispering, but she targeted me.

In the sixth, seventh and eighth grades, most of the teachers conducting a lesson would be going through "the motions", but their minds were elsewhere for certain. I had a teacher who spaced out during the recitation of a history lesson. I was going along when I saw the teacher close her eyes and shake her head; I stopped and said, "No?" Then she apologized for it and the lesson resumed. The thing is, she DID it. I never figured out where he mind was that day, but she never did it again.
