Narrator (normal speed): "Mr. and Mrs. Wilson had been thinking of inviting Mr. Foster to dinner for some time. Last Saturday they finally decided to telephone him. Mr. Wilson rang up and asked whether Mr. Foster could come to dinner on Sunday evening. Mr. Foster said he was sorry, for he had a previous engagement. He had promised to help a friend who was moving house. Mr. Wilson said, 'Oh, that's a pity. Perhaps we could arrange another evening?' Mr. Foster suggested the following Friday. They agreed, and Mr. Wilson thanked him."
