not sure about that :-)

She knows I would not listen to her on this subject.

The funny point is that she think we should push the kids to learn Chinese as a kid. But her example showed that learning environment is the most important in learning a language.

My son can carry some simple conversation in Chinese. The big problem is that he doesn't understand Chinese culture and got lost/confused most of time if the conversations go a little deeper. He is not interested in learning and I don't feel like to push him. Most of his life he is exposed to English and American Culture. I don't want to confuse him at this time. I think in the future if he feels it's worthy his effort, he can do the same as that boy in the conversation or even better. He needs a culture environment to really master a language.
