William was tall and thin and shy and awkward in school. His best social tool was that he played the piano, and so was recruited for school musicals, which placed him at rehearsals and cast parties with kids he would otherwise scarcely have known. He thought he would be either a pianist or a physicist, although he didn’t know anyone in Montana who did those things professionally. His piano teacher was a banker’s widow who gave lessons in her lace-curtained house, and his physics teacher was primarily the wrestling coach. But William could imagine another kind of life.
Does "social tool" mean skill?
