premise: I have a city teacher friend who 's class room had a better library than the school 's . I picked up a couple of books on music , biography and computer stuff . While browsing the biography section looking for anything related to the space program I was asked by someone if I knew a lot about computers . What gave it away ? What may be your reason for not getting books at the library ?
hypothesis: I knew of a place to go that had the computer books I wanted .
