I was feeling a little sad because my mother had lost her job, One day, while I (walk) on the street, I heard that a beautiful piece of piano music (play) above the noise of the people. I walked more slowly (find) out where it was coming from. Then I saw a young lady sitting at a piano.
She was singing songs about love, believing in yourself and keeping on (try). The way she was singing made me (relax). I stood there quietly, watching her playing in such a crowded square in New York. I thought that she must be brave enough to perform in front of so many people?
She noticed me. I walked over and (tell) her how good her music sounded. "Thank you," she said. "I have been going through a hard time recently, but you've made me hopeful again," I said to her.
"I'm glad that I could help," she replied. "Why are you so sad?"
"Well, my mom (lose) her job, and I'm not so sure what to do..."
"Did you notice the way you were walking? Your head was down," she said." (not be) upset, because opportunity comes in different ways and if your head is down, you might not see it. You should (smile) more and lift your head up."
I looked at her, amazed at how she was encouraging me." Why are you (play) the piano here now?" I asked her with a smile.
She explained that she saw a lot of unhappy people in the world and that she tried to cheer them up by playing music.
I smiled a little wider, realizing that no difficulties could stop me from going on.
