Dear Peter,
We discussed about the visit to Beijing last few weeks and decided to go therethis Friday.However,I amsorry to inform you that I could not make it.
I received an urgentcall from my uncle last night.He told me that my grandmother is sick and she is now in hospital.I am very worried about her and I shall go to visither inChangzhou this afternoon.
I would like to apologize for my sudden leave.I hope you may forgive me and allow me to postpone this Beijing trip to next month.Thank you,Peter.
Best Regards,
Winnie
