This one snuck up and clubbed me:
When people die, they leave a giant black space in your life. Or maybe the giant black space is filled with people who have died. Every week, Laura plays an Airwaves Archive, breathing life into recordings of old radio broadcasts. It seems to me that the part of radio that is always slipping away from us is the part that makes it so achingly compelling. We can archive everything we broadcast now, and we do, but we are still broadcasting, sending signals out from transmitters. The airwaves are already an archive, filled with murmuring voices drifting past each other out into space.
