The worst teacher I have ever met was my high school math teacher. He was a medium- height man who was in his thirties. He was overweight by about 20 or 30 kilograms because of his beer belly. When he was giving a class, he was given to putting a hand on his beer belly, touching it and doing a circular movement, which made him really look like a pregnant woman.

When he assigned the homework, he would grasp a piece of paper and said: ’enh, it’s just a piece of paper and you are supposed to finish it within 20 minutes.’ Nevertheless, it took us over an hour to finish it. As a result, some students decided to discuss this problem with him. But what he said was completely beyond our imagination. He said very arrogantly:’ that’s because you are too bad at math, I can finish it within 20 minutes.’ His response annoyed everyone in the class while he did not realize it. That was just one of those irresponsible things he did.
