Exception case for deception: Alzheimer's patients at an advanced stage cannot process truth; pacifying untrue statements may be the compassionate and functionally honest option since understanding is absent.

Mike uses the example of a friend's wife with progressing Alzheimer's who becomes agitated demanding to go to the store. Telling them "we'll go in a couple minutes" - though untrue - pacifies a situation where truth cannot be understood or received anyway. Mike suggests this may be a legitimate exception to the prohibition on lying.
