“The list of contacts in my smartphone’s address book has over a thousand entries. This is the result of an accumulation of almost two decades of collecting. It covers five cities, four schools, and three jobs. As I begin tapping the name of one entry, I get suggested several others. Maybe a former high school friend, though we no longer talk. Or the number of a mechanic, even though I no longer have a car. There are some names I just can’t situate. And, perhaps, someone that is no longer with us. I might take a moment to erase one or more of these entries from the past. But not the ones of the departed. Those I keep.”
