Isolation is both literal and metaphorical in Raise High the Roof Beam, Carpenters and Seymour: an Introduction. Narrator Buddy Glass is a member of the insular, peculiar, and alienating Glass family – a fact that predisposes him to isolation from the rest of the world. The difficulty of communication heightens this sense of isolation. How can Buddy connect to another individual, or even to the reader, when he can't communicate effectively? In "Roof Beam," Buddy suffers from isolation and loneliness even while surrounded by people. In "Seymour," he has progressed to physical isolation, writing from a lonely cabin in the woods.
