We may look at the world around us, but somehow we manage not to see it         31        whatever we’ve become used to suddenly  32        (disappear). Take, for example, the neatly-dressed woman I used to see.

For three years, no matter 33         the weather was like, she was always waiting at the bus stop around 8:00 a.m. On 34  ________   (snow) days, she wore heavy clothes and a pair of 35    ____________   (wool) gloves. Of course I remember all 36  _______   only after she was seen no more .It was 37       that I realized how much 1 expected to see her each morning.

“Did she have an accident? Something  38     ______   ?” I thought to myself about her disappearance. Now that she was gone, I felt that I 39   __________   (know) her. I began to realize that part of our daily life probably includes such chance meetings       40  _________   familiar strangers: the milkman you see at dawn, and the twin brothers you see at the library. Such people are important markers in our lives. They add weight to our sense of place and belonging.
