Don't get used to me (from the cycle "It has been heard")

It has been heard that shadows must not be trusted. Shadows always appear and follow us until at least one ray of light falls on us. Shadows are changeable and misleading. They change from softly light and barely noticeable to huge gigantic and sharp, but continue to follow everywhere until complete darkness. And then they disappear. All.

In the world of shadows, everything is different - people disappear there...

"Don't get used to the shadows. Don't get used to anything at all. Everything in this world is changeable. Don't get used to me either" - one shadow told the person, to which, as the  sound echoed: "You don't get used to me neither."
