The lost horse was born in a glacier so he had the color of ice and light. He was very happy when he was young but became blue when he grew older, and he felt an urge to leave. So he followed the river out of the glaciers and walked through deserts and prairies. But no matter how happy he was with his new friends and his lover, he couldn’t resist the calling of the river. Finally, he arrived at the sea and he could see all he had experienced in the waves, and he felt very calm there.
