I was feeling a little blue because my mother had lost her job. One day, while I was on the street, I heard the piano music and singing rising above the noise of the people. I walked more slowly to where it was coming from. Then I saw a young lady sitting at a piano. She was singing songs about love, yourself and keeping on trying. The way she was singing made me a little comfortable. I stood there ，watching her playing on such a crowded New York square. I thought that she must be enough to perform in front of so many people. She noticed me. I walked over and told her how good her sounded. “Thank you.” she said. “I have been going through a hard time recently, you’ve made me hopeful again.” I said to her. “I’m glad that I could help,” she replied, “Why are you so ?” “Well, my mom has lost her job, and I’m not sure what to do …” “Did you noticed the you were walking? Your head was down.” she said. “Don’t be upset, because comes in different ways and if your head is down, you might not see it. You should more… lift your head up.” I looked her, amazed at how she was encouraging me. “ are you playing the piano here?” I asked her with a smile. She that she saw a lot of unhappy people in the world and she tried to cheer up by playing music. I smiled a little wilder, realizing that no difficulties could stop me from going on.
