When I was ten, my mother worked all day, so I had to take care of my younger brother. At that time, my little brother was about four years old and he 1 mum all the time.
One day, after I had given him his dinner, he started crying for mum. He was so young and really needed mum. So I dressed him, 2 his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour later, I found that he lost a shoe while he was 3, I took him off my back and put him 4. I knew we needed to find that shoe, for our mother couldn't afford to buy new shoes. I had to go back to 5 it, so I told my brother to wait right there. A man heard it and stopped me just 6 I went away. He asked me, "You are leaving your brother here to find the shoe? What will you do if he is not here when you return?" I didn't know 7 to answer that question. He continued, "It's OK if you can't find the shoe, but it is not OK to lose your 8." Then he sent us to mum's workplace by taxi.
During my whole life I have received the 9 from many strangers. I feel sorry that I can't find them and say "10". I do not even remember what they looked like, but they taught me a lesson — people are more important than things.
