Good morning . Wilson Association .   This is Mr Brown speaking . I'd like to speak to Mr . Thomas , please .   I'm sorry , but Mr.Thomas left the office a few minutes ago .   That's bad ! I've been trying to call him for the last ten minutes , but your line has been busy . Will he be back soon ?   I'm afraid not . He's gone for the rest of the day .   Is there anywhere I can reach him ?   I don't believe so . He's going out of town on business . May I take a message ?   I have a business appointment with him for tomorrow morning at ten o'clock , but I'm afraid I can't make it .   Would you care to make another appointment ?   Unfortunately , I'm leaving town rather unexpectedly , and I may be gone for several days .   I see . I can tell Mr.Thomas that you phoned .   Thank you .   Bye-bye .
