Steve's unusual tags (слэш)

In in. Out out. In in. Out out.
Right. Left. Right. Left.
 
Steve runs, rhythm never faltering. In in. Out out. He runs without a destination. In in. Out out. He just runs. In in. Out out. He runs until his throat is dry, or his legs give out. In in. Out out. He runs until one of these happen, then takes a break. Once his body is operational, he starts again. In in. Out out. The clink of his tags being the only sound to be heard in the park except for his breaths. In in. Out out.
