When a voice came from the inside, “Alisa Camacho?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red haired man with a happy look in his eye. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 am by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other.
