““Without making any great show of it, Mather withdrew from him. Though they saw each other in company, and he was never obviously distant toward Edward, the friendship was never the same. Edward was in agonies when he considered that Mather was actually repelled by his behavior, but he did not have the courage to raise the subject. Besides, Mather made sure they were never alone together. At first Edward believed that his error was to have damaged Mather's pride by witnessing his humiliation, which Edward then compounded by acting as his champion, demonstrating that he was tough while Mather was a vulnerable weakling. Later on, Edward realized that what he had done was simply not cool, and his shame was all the greater. Street fighting did not go with poetry and irony, bebop or history. He was guilty of a lapse of taste. He was not the person he had thought. What he believed was an interesting quirk, a rough virtue, turned out to be a vulgarity. He was a country boy, a provincial idiot who thought a bare-knuckle swipe could impress a friend. It was a mortifying reappraisal. He was making one of the advances typical of early adulthood: the discovery that there were new values by which he preferred to be judged.””
