Besides the internal and external conflicts the other respondent posted, there are some other angles to explore in Jackson’s ironic short story “Charles.”
Another obvious external conflict is the one between Laurie and his kindergarten teacher, since he is constantly disruptive in ever more dramatic ways. Laurie struggles to behave properly in the restrictive environment of a classroom, and while he briefly behaves himself, Laurie acts out because of the stress that starting school has caused him.
Besides Laurie’s internal conflict to cope with the demands of school, Laurie’s mother experiences internal conflict as she struggles with addressing her son’s shifting attitude at home. She definitely notices a negative change in Laurie’s demeanor, but she doesn’t know how to acknowledge or correct the behaviors she finds unacceptable. The mother’s inability to decide how to fix these issues ultimately contributes to Laurie’s continued misbehaviors at school.
