In Chapter Five of The Catcher in the Rye, Holden tells the reader that his brother Allie's mitt has poems written all over it. He writes a composition for Stradlater describing Allie's mitt, which Stradlater does not appreciate at all.
Unfortunately, the reader never gets to read the composition. Students will use textual evidence to imagine what that composition was about. Students use both their creative writing skills and their understanding of the novel to write Stradlater's essay.
