There is a teacher in my daughters school that has made one student burn his paper because “only an idiot would write such trash” the same teacher made another student in that same class write a paper on why he is a ‘burden on the taxpayers’.
(some) Teachers are the biggest bully’s and abusers of children
Now I'll relate a real-life story about myself: I went off to college with that precious diploma, and majored in Physics and Math. The Physics department had its own computer, an IBM 1130. I threw myself at that machine, learning more about it than any of the professors knew. Eventually I made an attachment for that computer so that it could control a linear accelerator and take data from the target. It was necessary that I write a user's manual for that equipment. When I turned it in to the Physics professor in charge of the project, he said, "You did finish high school, didn't you? This is the most disorganized and illiterate piece of written trash I have ever seen." With no further comment, he threw it in the refuse can. He continued, saying, "Go rewrite this to show that you have an education, have important information you wish to impart, and give a damn".
I was crushed, yet I carefully rewrote that manual using the same style as the IBM manuals. He was happy with that version. I had a long career in engineering; and, writing good documentation was an important ingredient to my success.
I am very grateful to that Physics professor for kick-starting my ability to write proper documentation. I think you are foolish to imagine that harsh words from a teacher can be harmful. It was the tolerance of mediocrity that enabled poor quality work on my part.
