回复：凑个热闹给“失败的妈妈”表表看法

We do everything in a context. In this case, there is no context for the mother to do anything with this poor kid, let alone discipline. 

Love and trust are the base of everything. Here I see none.  The mother dumped her child with someon else for years, and now she think that he should be grateful because she brought him to Canada, and wants to give him an education.  And because of that, she thinks that she has the right to order him around. 

Everything we do has a consequence.  It does not matter what her reason was, she deserted her child for years.

Even parents who spent every minute loving and supporting their children have a difficult time with their teenagers....
