No. Why would someone I'm not close to be entitled to the details of my life and finances? Fuck that. A random person doesn't get access to my life just because we share DNA.
Hypothetical Situation
No, because it's not my information to share.
Me personally, a lie by omission is still a lie
We know, your post history of this account and your previous ones were all about you and your lack of discretion.
would you tell them your son is rich?
Hell no! That's not your information to share. That's your son's information. If he wants it shared, he'll share it.
Alternatively, if you are actively trying to have your son cut you out of private information he shares with you, this would be the fastest way to do it. Sharing that private info would be a betrayal of the trust he has with you.
Me personally, a lie by omission is still a lie, and hiding and keeping secrets from your family is wrong.
You...don't think you're allowed to keep anything private from your family? That is bizarre to me. I'm sure I could prove this wrong by asking you a few extra question about his knowledge of you, but I don't want to press this point.
You keep asking variations of the same question and getting the same answers. This isn't going to change no matter how many more times you ask. If you need your story to go a certain way, then just write it that way. People aren't always rational. If TV relationship dramas can get away with the dumbest excuses for creating tension, you can do the same.
