Dear Billy,
I am very sorry to inform you I won’t be able to go to Yangminshan with you on the occasion of the Moon Festival because I just got a phone call from the U.S.A. Ma and Pa will be back ahead of schedule in order that they can get together with us on this special holiday. They of the older generation consider the Moon Festival a reunion day on which all members of a family are requested to be back home no matter how far apart they are. Under such circumstances how could I hurt their feelings by going with you to watch the brilliant moon on the night of the Moon Festival? I hope can understand my situation and put our appointment off till the day following the Moon Festival. I was told the moon on that day is much more beautiful than the one on the very day of the festival. Besides, we shall be able to avoid the holiday rush and enjoy the quiet under the moon. Do you think it’s a good idea? I am looking forward to hearing from you soon. Regards. Cindy.
