It's terrible waiting for a phone call, or a message, or a conversational reply... that may never come. When you get that ringing in your ears... Superstition says someone somewhere is talking about you... but even if they are, there's no guarantee it's in a good and positive light. Worse so, was there ever a conversation started in the first place? Or was it you just talking to yourself all along.
What happens when the only ones who answer are the ones in your head? When you turn around and realize almost everyone has vanished... Where did everything change?
