It is a pity that I was not at home when you came to see me yesterday afternoon. The fact is that I had an engagement with some friends to accompany them to the cinema and I was ignorant of your visit. Not until nine o'clock in the evening did I come back. You must have been disappointed by my absence.
I hope you will stay one more week in this city. I will call on you on Tuesday morning at eight o'clock. Since this is the first time you come to Hangzhou, I will take you to visit some famous spots that you are expecting to. Please wait for me in your hotel at the appointed time.
Seriously, I am sorry to hear that you are not at home. I wanted to discuss with you the gathering organized by the students. Your wife welcomed me very warmly. But I had something to deal with so I did not wait too long. You do not have to apologize for it. The work will last a period of time. I will be waiting for you on Tuesday.
I am a little disappointed that I can't see you when I am on the trip to Hangzhou. You are so busy that you forget this matter. Although I have heard the beauty of Hangzhou, but my schedule is very tight. I'm afraid I have no time on Tuesday. So we can only meet next time when I come to Hangzhou, then you can introduce me some beautiful places and good tasted food.
