Although I love my life, it hasn’t been a lot of fun as I’ve been ill for 28 years. Music has always been a great love of mine and, in my 20s, when my was more manageable , I ten years as a professional singer in restaurants, playing and singing folk songs. it was years ago and times have changed. I live with mother on a country farm. Two years ago, I decided that I would need to have some kind of extra work to make up for my disability pension (残疾抚恤金). I needed to sleep in the afternoons, I was limited(限制) in my choices. I decided that I would consider to singing in restaurants. My family are all musicians, so I was when I went into our local music store. I explained that I wanted to sing again but using recorded karaoke music. I knew that discs were very expensive and I really didn’t have a lot of to get started. And often you find only three to four songs out of ten on a disc that you can use. When I told the owner of the shop about my , he gave me a long thoughtful . “This means a lot to you, doesn’t it?” he said. “Come with me.” He led me the crowded shop and to a bench with a large professional karaoke box on it. He placed his large hand on his treasure(财宝) and said, “I have 800 karaoke songs in here. You can take your pick and I’ll record them for you. That should get you started.” I could have cried. Thanking him, I made a time with him to listen to all the songs and choose that I could sing. I have come full circle with his help. His still warms my heart and makes me do just that bit extra, when I have the chance.
