MP--
I've been struggling with an unfortunate predilection to One Right Way for years and years.
Following Calamity Jane's suggestion, I Googled "wu wei" and found a number of what I'd term "windy" attempts to describe a state of mind that really isn't verbal.
Come to think of it, "Verbal" is probably part of our problem.
These aphorisms might help--if you're in the right mood for aphorisms:

A more Western approach is to decide exactly where your elbow starts and your beloved's nose begins.
I've never been particularly worried about how a companion's behavior will reflect on me. Even when one of my kids misbehaved, their transgression was not Making Me Look Like a Fool.
I'm getting less bitchy as I accept that many of Mr. Noddy's little ways really do not Distort the Fabric of the Universe or Smash Grecian Urns.
I will never agree that and orange shirt and grey sweatpants are a great color combination for wearing in public--but if he wants to wear an orange shirt with gray sweatpants (and blue socks and a brown baseball hat) he's doing no damage.
Mr. Noddy is diabetic. He's convinced that ice cream is a good cure for insulin shock. Ice cream is high in fat--which is digested slowly. I've told him. His doctors have told him. Mr. Noddy gets shocky and goes for the ice cream. I've learned not to argue--just to pass him the gummy bears as well. Damage is averted.
Mr. Noddy's memory is fraying--but that doesn't stop him from telling beloved stories that are out and out fabrications. This habit of re-writing history for his own greater glory had me tearing my hair out. I really wish he wouldn't tell whoppers, but if the Little Green People in the UFO's are judging the moral level of the human race, Mr. Noddy's whoppers are not likely to weigh heavily in determining the fate of humanity.
Accept that your Beloved's aberations are his business and resolve to keep your elbow out of his eye--both the left eye and the right eye.
If you're stuck with cleaning up after your Beloved's little misjudgements, you get to speak up. Otherwise, close your eyes and think of England.
