Dear Eric,

You wrote that your parents won't listen when you tell them things. I understand quite well that you feel frustrated and think your parents can't understand you.

I recommend that you talk to your parents calmly and tell them how you feel. It is not unusual for teenagers of your generation to feel that adults don't understand them. But your parents love you and want the best for you. They may not listen because they are busy or worried about other things. You should try to find a good time to talk, like during dinner or on the weekend. You can also write them a letter if talking is too hard.

I am sure that if you explain your feelings clearly, your parents will listen. After all, they care about you.

Best wishes,Li Hua
