What was the problem between margie and her teacher in the fun they had?

In "The Fun They Had" by Isaac Asimov, Margie struggles with her feelings towards her mechanical teacher, who she finds strict and unyielding. She is frustrated when her teacher gives her difficult lessons and doesn't adapt to her learning pace. Margie longs for the traditional school experience her mother described, where classes were taught by real humans and involved interaction with peers, contrasting sharply with her lonely, automated education. This conflict highlights her desire for a more engaging and relatable learning environment.
