| 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. | ||||
