When I was ten, my mother worked all day, so I had to take care of my younger sister. At that time, my little sister was about four years old and she missed mum    .
One day, after I had given her dinner, she started      for mum. She was so young and really needed mum. So I dressed her up, put on her    , carried her on my back and walked out. Soon she fell      .
About half an hour later, I found that she had lost a shoe while sleeping. I took her off my back and put her down.
