Thank you for your answer! On steemit i published this picture with a some little story that brouht into my mind. That it is:
"He looked around, but because of the rush of despair, he could not figure out how he had come here, because the world where he suddenly found himself was unfamiliar to him. And there was only one way out of here, away from despair.
He had tried many times to climb up on foot, but each time he fell down, unable to overcome the force pulling him to the ground.
Angry at himself, at his own helplessness, he wished that just one thing appeared here right now... bicycle. And it really suddenly appeared - shiny and brand new, as if it had just come from a store.
Clambering onto the saddle and gripping the handlebars, the man started up the steep slope, picking up speed quickly and flying like a bullet above the trees. But that wasn't enough. Just a little more and it will fall again. "No, no, not that!" With the last of his strength, pedaling and breathing furiously, the man exclaimed, " Rocket! Let the rocket appear! "
A bright dot streaked across the sky, speeding away up, overcoming the force of gravity. Now he knew the way to the top is opened. The man was returning home to the stars..."
