We may look at the world around us, but somehow we manage not to see it until whatever we’ve become used to suddenly disappears.36, for example, the neatly-dressed woman I37to see--or look at--on my way to work each morning.

For three years, no matter38the weather was like, she was always waiting at the bus stop around 8:00 a. m. On39days, she wore heavy clothes and a pair of woolen gloves. Summertime40out neat, belted cotton dresses and a hat pulled low over her sunglasses.41, she was an ordinary working woman. Of course, I42all this only after she was seen no more. It was then that I realized how43I expected to see her each morning. You might say I44her.

"Did she have an accident? Something45?" I thought to myself about her46Now that she was gone, I felt I had47her. I began to realize that part of our48life probably in- cludes such chance meetings with familiar49: the milkman you see at dawn, the woman who50walks her dog along the street every morning, the twin brothers you see at the library. Such people are51markers in our lives. They add weight to our52of places and belongings. Think about it.53, while walking to work, we mark where we are by54a certain building, why should we not mark where we are when we pass a familiar, though55, person?
