How to properly answer questions with indefinite pronouns?

Q. “Does anyone need to remind you of important things?”
--> “Yes, someone/somebody does.”
--> “No, anyone/anybody does.” (or doesn't?)

Q. “Does someone comfort you when you are down the dumps?”
--> “Yes, someone/somebody does.”
--> “No, anyone/anybody doesn't.” (or does?)

What are the proper ways to answer these questions, and (if possible) why?

Any help would be appreciated. Thanks in advance.
