You DUmbasses are miserable and butthurt over events that happened decades ago? Good.
Wrt such experiences, people that have any sense of self-worth and dignity would learn from such experiences as to how to avoid them in the future or how to combat them in a way that preserves their dignity. Instead, these crybabies sit around and wallow in self-pity for decades at a a time.
Example: I had a grade school teacher that tried to have me put into special ed simply because it took me longer than 2 minutes to do 25 problems. Of course, all of the ones that I completed (~75%) were correct. My dad ask her, you mean that if he hurried up and finished all 25 and he still missed 25% of them, that would be OK and we wouldn't be having this discussion. She said, "Yes." He looked at her and said, "That's the most stupid God Damned thing that I ever heard. No way will I let someone tht stupid put a label like that on my son." THis teacher continued to badger me throughout grade school.
When I was in my early 20's and in engineering school, I was working in a local grocery store and saw her. She had retired ~10 years prior. I made sure that I was the one to sack her groceries and carry them out for her. I said, Hello Mrs. West, She remembered me even though I was older and asked how and what I was doing these days. I told her that I was working my way towards a BS in electrical engineering. She got this puzzled look on her face and said, "that's hard, isn't it?" I said, " not really, I've been able to maintain a B average. Differential equations and Atomic Physics were tough but, I managed." With her jaw dragging the pavement, she immediately got into her car and sped off. That was a wonderful feeling. She came into the store many times after that and avoided me. That's how you deal with teachers that give you a hard time. You go back to them and show them how wrong and stupid they are.
