If someone told me:
I hope you have enjoyed your holiday.
What will be the best way to thank him/her? (in a full sentence)
The followings are what I can think of:
Thanks for the kind words.
Thanks for your hope(??).
Thanks for the answer guys.
One more thing to add is, I cannot directly reply to the original sentence with a "Thank you", because he immediately followed it with another question.
I hope you have enjoyed your holiday. How is the project going?
