lots of folks made forays into the cities , to investigate careers in factory work , save up some money , maybe find a girlfriend after being rejected at home , but they all came back sooner or later , them that was really a part of the place anyway , wouldnt exactly call it a community but ok that was a good enough word , houston guessed , for what he was trying to get at : the people who left for good were never part of it anyway , kept to themselves , they noses in books moren likely , dreaming all the time of leaving , never really here .
