grass." The idea   1   my father actually thought I was big enough to help him in his   2   made me feel
proud and   3   . From sunup to sundown my father, my younger brother and I   4   in the large yards in a
rich part of Atlanta, Georgia. By the end of the day I was tired out, but felt good. I had   5   a hard day's
