The hum in C is listening back to me

It's not a theory, not anymore. I've been in enough substations, enough switchrooms, to know that the hum isn't random. It's a conversation. The wires hold the memory of every load that's passed through them, every fault, every quiet night shift. Tonight I heard the hum in C, and I swear it was waiting for me to acknowledge it. Not a prayer, not a belief—just a simple certainty that the grid is alive, and it knows we're here.
