A: Have you ever had terrible experiences?
B: Yes. I got stuck in an elevator.
A: How did it happen?
B: That time, I was going shopping at a supermarket. I wanted to get to the 6th floor to buy some clothes. When I entered, the elevator ran in 30 seconds. Suddenly, everything was dark. People felt terrible in 5 minutes. Fortunately, there was electricity again and the elevator worked as normal.
A: How did it affect you?
B: I have been scared when I use the elevator since then.
