     Thank you very much for invite me to your birthday party in Saturday morning. I'd like to

come and I have to go to my hometown to see my grandparents. They were very old and unluckily

they are not in a good health recently. My mother has already made a telephone calling to them

and promised visit them with me this Saturday. My mother said we will stay at my grandparents'

the whole weekend. So I'm real sorry I can't attend your party. I do hope you will understand all

this. Here I wish you a lot fun on your birthday and many happy returns of the day.
