What is The Park

Grandma takes Jack to the park near her house after Ma's suicide attempt. On that first visit, she doesn't understand that he doesn't have any idea how to interact with other children. She realizes it later and takes Jack back in the early morning hours when he can play by himself. Grandma sees the park as something that Jack should greatly enjoy but Jack sees it as a challenge and one more strange thing that he has to learn about in the Outside world.
