Dear Glad,
I am sorry that I can not keep the appointment of meeting you at the airport next Monday.
Today I was told to solve an emergent problem in our branch company in Shanxi.And I will be absent the whole following week until nest Tuesday.
But I will tell you the route to my apartment.The map and address is attached in the enclosure.And you can get the duplicate key from my neighbour just by telling him your name.
Please enjoy yourself.I can not wait any longer to see you.
Yours,
Blabla
