Meanwhile, my father had mastered the old VCR-style programmable thermostats, but he doesn't really 'get' the Nest I gave him. Too high-tech and automatic for him. But, Mom likes changing the temperature from her iPad.
I see a vision of all our futures. Cranky old tech guy and hot-flashing old woman spend retirement in hacking war to set the indoor temperature with their phones/tablets/whatever we're using in a decade or two.
