"Don't call me that," he says.
"OK, sorry, young man," she adjusts.
When I read this I remember one of the things my son's pediatrician told me when we found out how gifted he was. She said "He's going to be smart enough to want to take control of everything...even your lives. You need to set the rules and stick by them or he'll walk all over you." So kindness, humility, courtesy, and self-sacrifice have been just as important as grades. Correcting an adult is a big no-no.
