I remember watching my sister and her husband calling each other frequently with, "How far are you away from home?" and just kind of scratched my head. (I think I have sinced talked them into enabling Find My.)

When my wife or I want to call a daughter we can see immediately if they are at work or at home... things like that are nice. There's also an indescribable sweetness to just looking longingly in on a daughter who is far away and wondering how her day is going. Empty nest blues? (Or maybe Miner at the Dial-A-View.)
