Save the voicemail from your grandpa. One day you’ll want to hear that exact voice again.

A voice is the part of somebody memory holds worst. You keep their face from photographs and their words from stories, and the sound goes surprisingly fast, which is why people are so shaken by hearing an old recording. Thirty seconds of something ordinary, about a lift or a birthday, turns out to be the thing worth having.

If there is a message sitting in your phone from someone older, save it somewhere it cannot be deleted by accident. You could also just record a call, with them knowing. No urgency is being suggested, only that this is easy now and impossible later.
