【答案解析】[范文]
Dear Jenny,
I"m writing the letter to express my terrible sorry for failing to attend your birthday party yesterday. You know. my grandpa suffered a sudden heart attack at that time. So I had to send him to the hospital and put myself to look after him wholeheartedly. I have prepared a present for you which I have asked James to bring to you.
I hope you will like it.
Love,
Nancy
