Today, I was at my job as a hostess. It was an especially hard day, and many customers had been rude to me. One man was sitting alone, eating at a table beside me. As I stood there, close to tears, he looked me in the eye and asked me what I wanted to do with my life. I told him I was going to school to be a teacher. When he left, he hugged me and handed me a twenty dollar bill. He said, "Make a difference, sweetheart," and left.
