The keys felt heavy in my hand. I’d been carrying them for so long - and I’d built them up so gradually, adding one here, a couple there over years, decades - that I’d never stopped and just held them, feeling the weight in my hand of all those ways into and out from all those places. But for a minute I felt the weight of those keys, and the doors they opened, and the lives behind those doors, and it was almost more than I could bear. And then I opened the door in front of me and did my job.
