I expect that even skeptics believe in - because they have experienced it - the phenomenon of knowing when one is being stared at. Right, Bill?

When I was the caretaker of a house museum and lived on the third floor I sometimes stood at a window and watched people as they passed by. Some of them were at a fairly great distance; the path outside the lawn led to a staircase (Juneau has many outdoor staircases) and I often continued watching them until they went out of sight more than a block away.

Some pedestrians were obviously aware of being viewed. Many of them looked all 'round; some of them even stopped in their tracks. I have frequently said that the people who 'felt' my eyes are the ones I want to know. Anyone can 'send'.
