Viết lá thư chấp nhận việc đi sinh nhật

my friend

After reading your birthday invitation, I have decided to go. Each person has only one birthday each year, so my friend's birthday cannot be missed. I will arrange a time to attend your birthday on time.

See you at the party

Dear Hai Anh, 

It was so nice to receive your birthday invitation yesterday. We all know that we haven't seen each other for a long time and I miss you so badly. Therefore, I really look forward to see you at your birthday party next week. 

Thanks for your invitation and I will certainly come!

Your friend,
