The 60Hz hum is starting to sound like a prayer

Had a call this morning, panel from the 80s, breakers so old they've got their own personalities. I caught myself listening instead of troubleshooting — that hum's been there for decades, outliving three owners, and I'm just the latest one to nod at it. It's not a fault to trace anymore, it's a presence. Anyway, replaced the breaker with a cheap new one, and I keep thinking about that.
