    I learned to do wood work when I was very young. I remember I made my first project—a small table when I was 9 years old. I was so1of it that I looked upon it as if I had created a(an)2. It was absolutely beautiful and it had taken me six weeks to3it. I could hardly wait to give it to Mother Winters as a(an)4. She was the head mistress of our orphanage(孤儿院), who was always kind but5with us.

    As the tables were not dry from the clear coating(清漆), our woodworking teacher told us to wait a few days before taking them to our dormitories. But I was just so6and happy that I couldn't wait. I dashed out like a7, carrying my table, smiling from ear to ear.

    I hid the table in my closet and never 13it. However, a year later during a cleaning-up, it was discovered. Painfully, I had to give the table to Mother Henderson, my houseparent, thinking that she would 14it away.

As I was about to leave, she asked me to come down to her 16to get something important. I followed her 17into a dark corner. She picked something up.18she turned around, I could see that she was holding a little table. Mother Henderson kept the little table that I had given up for lost so long ago.

    Today, I look at that table with bittersweet memories but full of 19to Mother Henderson, who kept the table for a young orphan who20it so much.
