Dear Jay,
Thank you for inviting me to your farewell party. I know that you really want me to take part in=> join in it.
But I regret deeply to say that  I cannot attend your party. I've just known that my cousin's wedding is at the same day as your party. I'm really confused=> in two minds about whether to go to my cousin's wedding or to attend your farewell party=> not. But I am a responsible family member, I finally decided=> made up my mind to come to the wedding.
I wish that you don't get=> feel upset. At the end of the letter=> Anyway, I want to say that I really had a great time when we studied together. Also=> moreover, I hope you will become a good student even though we don't study together. (Hope you and your family happy!)
Sincerely yours,
Jennifer
