It was sunny last Saturday. I determined buy two novels and some magazines, though I went to a bookstore with my four-year-old sister Jenny. There are lots of people in the crowd bookstore. There I saw my friend Lisa. As we hadn’t seen each other for a long time, we talked for a while. When I said goodbye lo Lisa, I couldn’t find Jenny at all. She got missing! I was so worried that I called her names “Jenny” again and again, but anybody answered. About fifteen minutes late, I found my sister in an only toy shop near the bookstore. A shop assistant (售货员) was played with her. Thank for God!
