How do you do, Mr. Smith? This is Lili. I'm calling to thank you for the wonderful dinner we had yesterday. I enjoyed it very much.
You're welcome. I'd like you to join us for dinner again sometime.
Thank you, Mr. Smith. I'm returning to China today.
Today?
Yes. I appreciate all help and in particular, all the time that you've spent on my account during my stay here.
Don't mention it. I am pleased to help you.
If there's anything that I can help you in the future, please let me know.
I'll do that. Thank you. Have a safe trip home.
