I once had this teacher who taught us english. She was very strict but if you follow her instructions, then nothing will happen to you. The problem was we have an Indian classmate, and she will always joke about classmate A being "black". we were 11 at that time, and I didn't think that was right. For example, we were doing a short essay about a taekwondo club, which had a tiger as the logo. She used that opportunity to call A a "black tiger". She would also call A black many times and even called A a monkey. I really disliked that teacher, but luckily she's not teaching me anymore. I also had one classmate whose parents where divorced, and she knew about it. Because B's parents where divorced, B was always a rebellious type. One time, when B made her angry, she said "Why are you like this? Is it because you have no parents to teach you manners?" I found that very offensive because you don't know what people are going through and you don't have any rights to say about their parents.That's pretty much all I can remember about the things my english teacher had done.
