Dear Bruce,
Thank you for inviting me to the get-together on Sunday. I am very interested and would love to have a warm get-together with you. But unfortunately, I will have a very important competition to take part in on Sunday, and won’t be back until next Monday. I am very sorry for not being able to join you. But we can make a date for some other time when it is convenient for all of us. I think we will have a wonderful time then.
I hope you will have a good time this weekend.
Yours,
Li Hua
