For those of us drivers with many years on the same route. We have experienced sociological observations. For instance in my case. Delivering to a home with children, who as the years go by, some turn for the worst and others live as responsible adults. I, can recall seeing over some years, a young boy. Who went from riding a bycicle to hanging out with gangs. I would wave to him as a child and now as an adult, while standing on the corner with His hommies.
