It's very kind of you to see me off.
Not at all. I wish you a pleasant trip on behalf of my company and in my own name.
Thank you. Hope to see you again.
It's a pity you can't stay longer. I hope you'll visit our company in the near future.
I hope so,too. Thank you for everything you've done for me during my stay here.
You're welcome. Please see hello to your family.
I will. See you.
See you.
