Responding rudely or disrespectfully to someone, especially when they are asking about your children's well-being, is not appropriate or recommended.
Instead, if you don't feel comfortable discussing your children or prefer to keep that information private, you can respond politely but firmly. For example, you could say something like:
"I appreciate your concern, but I prefer not to discuss my children's personal lives."
Remember, being kind and respectful in your interactions helps maintain healthy relationships with others. If you find the question intrusive or uncomfortable, it's okay to set boundaries politely.
