About twenty years ago I asked a very close friend of mine why some people acted and treated me so strangely when I was around them and she said, "Because sometimes you scare the hell out of them by knowing things that you shouldn't or couldn't possibly know."
What's funny about that was that whatever it was that I was saying it was totally unconscious on my part. It wasn't like I was trying to do a reading or read their thoughts or anything like that. And I certainly never really knew that I was doing that before she said that. However, now all these years later, whenever anyone looks at me really wierdly I instantly revert back to what she said.
I can relate to your poem!
