Keeping something private doesn’t mean you’re hiding it. Some things are just yours.

Privacy and secrecy get treated as the same thing, and they are not. Secrecy conceals something that would change how people judge you if they knew. Privacy just means a part of your life is not on general release, which requires no justification at all, even to people who love you.

If someone presses and you feel obliged to explain why you are not saying, you can decline that too. A plain line works better than a reason, because a reason invites negotiation. Notice too whether you are calling something private when you know it is really hidden.
