have to go to my hometown to see my grandparents. They were very old and unluckily they are in a bad
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' for 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.
