If I had an inconsequential time machine, I would go explain to my fifth-grade self what a smart phone was. That way every time a teacher said “are you going to carry around a calculator the rest of your life?” I could answer “yeah, and it will be smaller than the ones in our classroom and I can watch Nickelodeon on it.” You may wonder what this has to do with a series about families, which is a good sign that you should be here on Sunday to find out.
