Last Saturday, I decided to go to a movie in the evening. My little sister said that she wanted to go with me because she was bored at home. When we got to the theater, a lot of people 1 there to buy tickets. I saw a friend in the crowd, so I walked up and talked to him for a while. When we finished talking, I found my sister was gone! I 2 her name loudly and looked for her for thirty minutes. Everyone was looking at me. Finally, I found my sister in a toyshop near the theater. She was playing happily there.

We 3 the movie that night and went home early. I have learned from this experience to be more careful if I have to take my sister out with me again.
