Father, Mother, and Dweezil took very different roads to death. All three were along in years and suffering as their ends drew near, but Dweezil the cat got the best deal by far. A vet solved his problems in seconds, and there were no dubious religious ethics to make a mess of it.
My parents had been out of the religion loop all their lives: they were not atheists, not agnostics, not humanists—just out-of-the-loopers. They eventually divorced and remarried—Mom to another “religious disassociate" and Dad to a cafeteria Catholic who viewed ethics as a menu and sent whatever she didn’t like back to the kitchen.
