you are (not) the only exception

I have this dream.. Where we go back to that old banch and talk about us. And you're there with me, for good. There's no fear, no anguish, or hurry. And for a moment all I can hear is your kind low voice, your childish 5-year-old laugh, and you breathing deeply. All I see is you. All I want is you. All I need is you.
Then all of sudden the day fades out. It's dark as if the sun has forgotten to rise. I feel blind and lost. I feel alone. I'm awake. Sometimes waking up has its disadvantages.
For a moment you were here, and here you'd stay. In our eternity, we'd live.
But you're gone.. oh! darling, I've finally learned to stop dreaming.
People always leave. With no exceptions.
