The Occasional Silence

You can walk into a room and spot them. They seem fine when you talk to them but every now and again, across the room, you catch them looking off into the distance at an invisible point that maybe, they once reached. They laugh a little different. They hesitate a little more. Now they know what it feels like. And something about their eyes when they listen to music says

"Turn it up until my ears bleed. Let it be the last thing I hear."
