At the beginning of Freak the Mighty, Max lives in a friends-free zone. But Freak won't have any of it, and pulls Max into a friendship that totally turns his world upside down. Max starts doing better in school, he's more polite to his grandparents, and he spends more time out of the down under. Yeah, this is some seriously positive peer pressure we've got going on.
Friendship is more important than family to Max.
Freak and Max's friendship benefits Max more than it benefits Freak.
