Why is it that we heap scorn on "deadbeat" parents who fail to take care of underage children, but excuse adult children who don't take care of their feeble parents?Perhaps it's because caring for children—no matter how many diapers and scrapes must be tended to—is a joyful experience, while aging involves untold sadness and indignity.
Maybe it has something to do with our unwillingness to confront death.
