Right, so i wrote a piece. I'm not 100% satisfied.
He was in the mountains, seeking solitude. The mountains were feared, and seldom disturbed. Many went in and never returned. But he was different. Unlike the others, he was not clumsy, and was far stronger than all of the villagers. For that reason he was never fully accepted into the society. For that reason he sought solitude in the mountains. He was challenging the mountains, daring them to consume him. He felt no fear, for he had nothing to lose. Perhaps if he returned from the mountains he would be regarded a hero, but the people were cruel. They do not accept those different from the majority.
In one hand he had a spear, in the other, he held a torch. He brought neither food nor water with him, the reason was unknown. He made his way through the mountains, and arrived at a stream. It was tiny, but vital. All great rivers start out as small streams, just like humans. Every warrior starts off as a baby, gradually growing. Without that stream, a river would shrink. Every tiny thing was important. There was little vegetation around the stream, and it enhanced how lonely the puny stream was. No animals were visiting, no bugs, and no reptiles. He wanted to accompany the stream to the place where it would no longer be isolated.
So he set off again, walking along the stream. Gradually it grew, it became wider, deeper. Its pace became faster, and he was no longer able to keep up with it. The water ran, throwing itself forward, away from the lonely place. It arrived at its destination. And so the water leaves its source eagerly, like a bird leaving for south, but never to return.
He was like the water, leaving his home to a place where seclusion was fantasy.
