While my brain resets after trying to solve the equation, I think there could be value in reaching out to those you care about to let them know if the May 21 end-of-days they believe in fails to occur, that you think no less of them and would be glad to help them get over their disappointment with a home-cooked meal and a sympathetic ear. We all have a belief or two that the majority might not share and these are the neighbors we count on during potential emergencies.

I seem to recall something about glass houses and stones.
