    That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one
in the morning after a tiring practice at the theatre. With the first performance only a week   1 , I was still
learning my lines. I was having   2   dealing with my part-time job at the bank and my acting at night at the
same time.
     As I walked, I thought seriously about   3 up both acting and San Francisco. City life had become too
much for me. As I walked down   4   streets under tall buildings, I felt very small and cold. I began running,
both to keep   5 and to keep away from any possible   6 . Very few people were still out except a few
sad-looking homeless people under blankets.
     About a block from my apartment, I heard a sound behind me. I   7 quickly, half   8 to see someone
with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me
  9  , so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize
  10 the noise had been. It had been my  11  falling to the sidewalk.
     Suddenly I wasn't cold or tired anymore. I ran out of the door and back to   12 I'd heard the noise.
Although I   13 the sidewalk anxiously for fifteen minutes, my wallet was  14  to be found.
     I was about to give up the search when I heard the garbage truck pull up to the sidewalk next to me. When
a voice called from the   15 ,"Alisa Camacho?" I thought I was  16   . How could this man know my name?
The door opened, and out jumped a small red-haired man with an amused look in his eyes."Is this what you're
looking for?" he asked,   17 up a small square shape.
     It was nearly 3 a.m. by the time I got into bed. I wouldn't get much   18 that night, but I had gotten my
wallet back. I also had gotten back some   19 of city life. I realized that the city couldn't be a bad place as
long as people were   20 to help each other.
