Trying to figure this out, a friend asked me this today. You can move in a straight line and still keep your head turned toward each other, and considering it's a field they can't have seen each other that well. Were they walking parallel to each other?One summer evening, as I was walking in the fields, I heard somebody behind me calling out my name. I turned round, and saw a friend of mine, at the distance of 400 yards, approaching to join me. We each of us moved 200 yards, with our faces towards the other, in a direct line yet we were still 400 yards asunder. How could this be?
