Describe how Zinkoff reacts to his new freedom in chapter 2

In Chapter 2, "The Bright Wide World," Zinkoff is introduced to the reader as one of the new group of boys who have been living at home all their lives, but now stand alone on their front steps, ready to go somewhere by themselves for the first time. Zinkoff is thrilled by this, and he laughs with joy. No grown-up is holding his hand and in front of him is the bright wide world.

He takes off running and can hardly believe how fast and free he feels. It seems he is going so fast that he is surprised when a car passes him. Thrilled by his freedom, he laughs, and stomps on the sidewalk as if it were a puddle. He cannot see his house. He turns right, running fast. It occurs to him that if he keeps turning right, he can run forever. He shouts with glee.
