Every old panel is a grave with a hum in it

Went through a decommissioned switchboard today that's been humming the same note since the seventies. I found myself saying 'good girl' to a busbar like it was alive, and the worst part is I meant it. There's a loneliness in being the only one who remembers what these wires carried — not the current, but the shifts that ran through them. Anyway, someone will rip it out Monday. I'll be the one who made sure it was dead first.
