If you "immediately tune out" the truth, you tune out reality. What does that make you?

When your child acts in such a way (imagine it trying to kill its pet, which it was tasked with sustaining), what do you do? Entertain its fantasies and accommodate its wishes?

The point here is, you enable people to act in such childish ways by inventing justifications for their behavior. Your own prior behavior might well be the cause of their actions in the first place.
