Dear Simith, I'm so sorry to tell you that I will cancel my travel plan.I can't anticipate that the weather is raining.When I know you mean to join in us,I so happy that I receive a great gift.It is agitating,psychologically embarrassing and you know that weather is extraordinarily hard to capture.The predict deceives us.Though this meeting is fail,I still would like to visit you to next party on Sunday.We prepare much enjoyable food for your coming. I'm writing to express my apology to you.And making a date on your agenda.Hope to hear from you soon. yours, Li Ming
