Well , I'm afraid I must be going now . I have no idea it was so late .   Stay for dinner with us .   I'm afraid I can't . I have a dinner party at seven tonight . You see , I am going to England the day after tomorrow .   Well , I won't keep you then . It was very nice of you to come to see me .   It has been a pleasure . Goodbye .   Goodbye . Thank you again for coming .
