When I was a little boy, I spent three long summers playing in the tops of trees. I was usually an airplane pilot, but sometimes I was an ape-man like Tarzan. This started when I was eight. But when I was eleven, I fell out of a tree and broke my arm. After that I played only on the ground. I was too poor to own a bicycle, but I did have some skates.That´s when I began to skate to the library and to read at least one book every week. But sometimes at night I still dreamed I was playing in the trees. The books taught me to use my head, but the trees taught me to use my whole body.
