Mr. Smith: Good morning, Mr. Blackwell. Is our meeting still on?
Mr. Blackwell: Good morning, Mr. Smith. Of course.
Mr. Smith: Outstanding. Could we postpone it by half an hour?
Mr. Blackwell: Why?
Mr. Smith: I feel I won't be able to prepare the documents for you in time. We have a little emergency at the office.
Mr. Blackwell: Very well. Half an hour later it is.
Mr. Smith and Mr. Blackwell are going to meet half an hour later than planned.
