Stuck his head out of this window
Pay attention to Holden’s references to windows. There are well over thirty throughout the novel.
In this particular flashback, Holden is having fun, throwing the football around with his friends when a teacher interrupts to tell them that they have to get ready for dinner. In a lot of prep schools, being at dinner is considered a responsibility — you have to be well-dressed, on time, and in the right place. being at dinner is one of Holden’s first glimpses of adult responsibility — since he doesn’t have parents around to force him to do it. When Mr. Zambesi sticks his head out the window, it represents this realization’s infiltration of Holden’s still very immature world. He doesn’t want to grow up, but flashbacks like these make him realize that he has to.
