We pass them each day, unseeing their faces and ignoring their plight at every traffic light. The idyllic environment of an air-conditioned car escapes the heat, dust and dirt that envelops everyone outside your tinted windows. When their antics do catch your attention you look at them with amusement, disregard and even disdain. You could choose to see them as beggars, ragamuffins and street urchins. You may regard them as a necessary evil and grudgingly accept their role as cleaners. But then like most people, you would have seen only the visible and missed what could be the essence of life itself.
