g. When I turned around I saw my friend walk off the trail about 100 feet ahead of me, and walk towards the edge of the lake. He had this mischievous grin on his face. I kept my eye on him as I walked towards where he stepped off the trail; I had the thought he was trying to hide on me. So when I got to where he stepped off the trail, I ran ahead with the intention of hiding on him. I ran a minute maybe two and as I rounded a turn in the trail my friend was standing there calmly waiting for me. I was shocked. There is no way he could have got here as I just left him in my dust. I was looking back at him when I ran off and knew he was behind me. Only one trail, so no way for him to get to where I found him. What was this? Can anyone offer an explanation?
