Dear Dr Fang,

How are you? I am writing to ask for some   36  about how to help my 15-year-old son. At the moment, he refuses to do almost anything his mother and I ask him to do. He is our only child and we treat him very   37 . Though his grandparents buy him many things, yet he is still   38  to them and often shouts at them. He also   39  to spend time with us or do as we tell him.

Recently, he has been refusing to do his homework, and instead insists on   40  his time listening to foreign music. I cannot understand that   41 , and I don’t like it. Meanwhile, he spends too much time in Internet cafes, where he either plays games   42  chats on the Internet. He is wasting valuable time during this   43  period in his life!

What shall I do? I am worried about it.   44  I keep allowing him to do what he wants, he may fail at school, or worse. How can I help my son   45  hurting our feelings?

Best regards
