When I was a child, I got lost in the subway station. I was scared. My parents were on the train. I was crying.
A stranger with an older child asked me what happened. I told them that I was lost. I told them about the door closing and that I wasn't on the train with my parents.
After I told the person how I got lost, they waited with me for my parents to come back to pick me up, but they didn't come back.
The stranger and her child stayed with me and I went to Chinatown and telephoned my father and he picked me up. I was so happy.
