One day, while I was 1 in the street, I heard the piano music and singing rising above the noise of the people. I walked more slowly to 2 where it was coming from. Then I saw a young lady siting at a piano.
She was singing songs about love, 3 yourself and keeping on trying. The way she was singing made me a little comfortable. I stood there 4 , watching her playing on such a crowded square. I thought that she must be 5 enough to perform in front of so many people. She noticed me. I walked over and told her how good her 6 sounded. "Thank you," she said.
"I have been going through a hard time recently, 7 you've made me hopeful again," I said to her.
"I'm glad that I could help," she replied. "Why are you so 8 ?"
"Well, my mum has lost her job, and I'm not sure what to do…"
"Did you notice the 9 you were walking? Your head was down," she said. "Don't be upset, because 10 comes in different ways and if your head is down, you might not see it. You should 11 more, and lift your head up."
I looked 12 her, amazed at how she was encouraging （鼓励） me. "13 are you playing the piano here?" I asked her with a smile. She 14 that she saw a lot of unhappy people in the world and she tried to cheer 15 up by playing music.
I smiled a little wider, realizing that no difficulties could stop me from going on.
