Ma is pretty patient, but Jack is patient, too. Even at a young age, he realizes that he sometimes forgets things, but this doesn't frustrate him. He just knows he has to be reminded of things, and everything will be okay.

This is a pretty profound line from a five-year-old. Most kids don't learn to take care of their things for a very, very long time. Jack has learned this lesson pretty early.

Revealing to Jack that TV is kind of real opens up a whole new world for Jack to learn about. This revelation changes Jack's entire world, making him think about everything in a whole new way.
