Dad is a very young looking 12 years old in this staff photo of the Aiken Preparatory School News 1948-1949.
He recounts some of the school's customs in his best known short story "So Much Unfairness of Things" published in The New Yorker June 2, 1962.
"For example, new boys, or "toads," still must obey the Toad Code. They must be courteous to old boys and faculty. They must know the school song and cheers by the end of the second week. They must know the names of all members of the faculty and the varsity football team. They must hold doors open for old boys, and see that old boys are served first in the dining room. And they must "run relay"--meaning that they have to wake up the old boys in the morning when they wish to be wakened and see that they are not disturbed when they wish to sleep."
