One of my favorite minor characters in To Kill a Mockingbird is Scout's small but gallant classmate, Little Chuck Little. Although Chuck is "among the most diminutive of men," he is head-and-shoulders above the rest of the boys in the class when it comes to taking quick action. Little Chuck immediately steps in to comfort Miss Caroline when she becomes unnerved about the "cooties" found in Burris Ewell's hair, and when Burris threatens the teacher, it is Little Chuck who comes to her rescue. Reaching for his pocketknife, Chuck squared off against the much larger son of Bob Ewell.
"Watch your step, Burris," he said. "I'd soon's kill you as look at you. Now go home." (Chapter 3)
After Burris storms out of the classroom, calling Miss Caroline " 'a snot-nosed slut of a schoolteacher,' " Little Chuck joins the rest of the children when they "clustered around her desk... to comfort her." Scout obviously thinks highly of him.
Little Chuck... didn't know where his next meal was coming from, but he was a born gentleman." (Chapter 3)
