How to respond to delusion

Sometimes people present us with delusion. They're perfect children of God, as are we, but today they're presenting us with delusion. Yesterday we had our own delusional narrative; today it's their turn.

Do we have spiritual consent to challenge? If so, maybe challenge if it's within the remit of the role.

If not, we're presented apparently with the choice either of co-signing or of saying literally nothing and rightly being charged with passive aggression.

What does a person do?

Well, here are some off-the-shelf responses that, if used politely and kindly, will enable us to stay in the game but keep our powder dry, mind our own business, and keep our mouths (largely) shut:

(1) Yes
(2) No
(3) Really?
(4) Gosh!
(5) OK
(6) Thanks!
