What is the proper response to someone attempting to nosily inquire about personal matters?

In situations where someone is nosily inquiring about personal matters, the most appropriate response would be one that asserts boundaries and maintains privacy. While "pry" generally refers to trying to obtain information in an intrusive manner, the context of the question suggests that the focus should be on setting limits.

The concept informs us that a good response to such inquiries might involve quelling the probing by calmly but firmly asserting that such personal topics are not open for discussion. This serves two purposes: it protects your own privacy and can also signal to the inquirer that their approach is inappropriate.

The other terms do not adequately reflect the appropriate course of action. "Quench," for instance, relates more to extinguishing something, and would not be relevant in this context. Similarly, while "quell" suggests suppressing something, it is a bit more forceful than simply asserting a boundary. The term "prudent" denotes wisdom or caution rather than a direct response to the inquiry itself. Thus, focusing on managing one's privacy through a measured and assertive response, which would align closely with the action of quelling, is the means to address such situations effectively.
