#Person1#: Where are you going, Jane?
#Person2#: I'm going to the hospital to see Susan.
#Person1#: I saw her yesterday. She was a little better.
#Person2#: Must I catch a number 7 bus to get there?
#Person1#: No, you needn't. A number 13 bus will also take you to the hospital.
#Person2#: Number 13 buses run much more frequently, don't they?
#Person1#: Yes. I caught a number 7 bus yesterday, and they said I had taken a wrong bus.
#Person2#: Thank you, Henry. I'll get a number 13.
#Person1#: But number 13 buses leave from the center of town. You'll have to walk two miles to catch one.
