Hello , Kevin . I hate to do this , but I have to cancel our appointment .   Oh , no ! Why ? I was looking forward to seeing you at my new place .   Yeah , I really wanted to come , too . But something unexpected in Shanghai have come up . I have to fly out for a few days , but I'll be back soon .   No problem . Call me when you get back .   I should have some free time next week . Say , next Wednesday evening ?   That's good for me , but do you think you'll be back by then ? I'd really like to see you .
