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 I 37  to see -- or look at -- on my way to work each morning.

     For three years, no matter  38 the weather was like, she was always waiting at the bus stop around 8:00 am. On   39   days, she wore heavy clothes and a pair of woolen gloves. Summertime  40   out neat, belted cotton dresses and a hat pulled low over her sunglasses.  41   , she was an ordinary working woman. Of course, I  42   all this only after she was seen no more. It was then that I realized how  43  I expected to see her each morning. You might say I   44   her.

“Did she have an accident? Something  45 ?” I thought to myself about her  46  .  Now that she was gone, I felt I had  47  her. I began to realize that part of our  48   life probably includes such chance meetings with familiar 49 : the milkman you see at dawn, the woman who  50   walks her dog along the street every morning, the twin brothers you see at the library. Such people are   51   markers in our lives. They add weight to our  52   of place and belonging.
