I might come across the Professor then on his after dinner stroll; and as often as not, he would be accompanied by my father, who would stop me and demand (partly, I thought, to impress the Professor) where I was off to or where I had been; insisting, with more than his usual force, that I come home right away, with no argument I spent long hours cycling back and forth between our house and Ross McDowell or Jimmy Larwood's, my friends from school, and the Professor's house was always on the route, I was always aboard and waiting for something significant to occur, for life somehow to declare it self and catch me up I rode my bike in slow circles or figures-of-eight, took it for sprints across the gravel of the park, or simply hung motionless in the saddle, balanced and waiting.
