Your kids may do many things about which you haven’t the foggiest notion. that’s good cuz it means they respect you enough not to let it slip.
Well, can’t prove it either way, so it becomes a parents prerogative to believe the best about their children, not just blind belief and naiveté but performance based observation nearly 100 years of cumulative parent/child relationships.
Sad to think you assume that your kids just lie and quibble or withhold from you.
Sure, my children have had tough times, divorces, even a few legal issues, but none are in jail or ought o be, none are flotsam a or jetsam and debris on the side of the road, all pay taxes, are professionally employed and productive- now, I do have nephew who is a derelict, but he isn’t close so I/we had no chance of influence either way.
