The older woman walking her two dogs toward us on the sidewalk notices us standing to one side, giving her right-of-way at appropriate social distance, but her expression is impossible to read beneath the surgical mask that everyone on the street seems to be sporting in one way or another these days.
"Is that an iPhone?" she asks as she approaches us, to Katie who is posting something as we wait for her to pass.
"Yes it is," Katie answers, looking up.
"Facial recognition doesn't work anymore," she says, and we can hear the smile in her voice.
