How to reply to the ambiguous information of the pursuer?

You can reply to something shorter, such as "Uh-huh, oh, okay, uh-huh, okay, thanks, no, I'll talk about it later, I'm sorry". I think your reply is ambiguous, and he will feel that he has the opportunity and will continue to help you. Just try to be indifferent. This is how I get rid of these ambiguous guys.
