There was nthing t see, but I knew it was there. After abut a mile, a stranger appeared beside the path. “Am I ging the right way?” I asked. He knew where I was ging. “Yes,” he replied, “yu’ll get there in five minutes.” Finally, I came t sme rcks and stpped. I lked ver them, but it was silent and there was n sign f it.
