My dear teacher, I had a fight with my parents yesterday. I upset and unhappy now. I just can't understand parents are always asking" Why don't you finish your homework? ""Why couldn't you just get good grades? "I feel so nervous I can't get enough sleep and my hair turns white. I know importance of study because it can make a difference to my life. But it is not to just get good grades at school. Kids these days have too stress at school. We have to do chores and take care ourselves. So why couldn't parents make relaxed on weekends and anyway it is very common that our grades drop sometimes, right? I know it is very important to communicate with our parents, but I don't how to do it. Could you please give me some?
