I got lost in my own neighborhood last week. Not badly lost, just briefly confused - turned a corner I'd turned a hundred times and didn't recognize where I was for about thirty seconds. I looked at my phone to check the map before I looked up at the street signs, which were right there. I found my way back in two minutes. But I've been thinking about those thirty seconds. I've lived here for four years. I used to know this place in my body, the way you know a place you've walked hundreds of times.

I think I stopped navigating at some point and started following. The blue dot moves and I move with it and the landmarks became irrelevant because the app already knows. But the app-knowing and the me-knowing are not the same thing, and I've been letting the first one replace the second without noticing. If the phone died and I needed to get home, I could probably do it. Probably. How confident are you in that answer for your own neighborhood? How much of where you live do you actually know?
