Hello, this is Jonason speaking.
Hello, Jonason, I am Kasy. I am sorry to tell you that I may not attend your birthday party this weekend.
Oh, what's up?
Nothing much.., but...
What's happened then?
I have an important exam at that time.
If so, I think we can hold the party ahead of time. What do you think about it?
Yeah, It is a good idea. I can't agree more.
Great and I wish you success.
Thank you, happy birthday to you.
