M: Where are you going, Jane?
W: I’m going to the hospital to see Susan Green.
M: I saw her yesterday. She was a little better.
W: Must I catch a No.7 bus to get there?

W: No.13 buses run much more frequently, don’t they?

M: But No.13 buses leave from the centre of town. You’ 11 have to walk two miles to catch one.
