When I was ten, my mother worked all day so I had to babysit my 1 brother. At that time my little
brother was about four years old and he missed mum all the time.
One day, after we had dinner, he started crying for mum. So I dressed him, put on his 2 , carried
him on my back and walked 3 . Soon he fell asleep. About 20 minutes later, I found one of his shoes 4 while sleeping. I took him off my back and put him down. I knew we needed to find that shoe because
our mum 5 buy new shoes. We had to go back to find 6 . So I told my brother to wait right there. A
man heard it and 7 me just before I walked away. He asked me, " You are leaving your brother to find
the shoe? What would you 8 if he is not here when you come back?" I did not know how to answer that question. He said again, " It's OK if you can't find the shoe, 9 it is not OK to lose your brother." Then he sent us to mum's workplace by taxi. I do not even remember what the man's face looked like, but he
taught me a lesson-People are 10 important than things.
