Bill, I know that you don't really believe that I know what I know. Maybe you don't even think that anything is really knowable the way I go about knowing. This, however, does not mean that I don't know what I do know or that you don't know what you do know. All it means is I know that I know things that you don't know. And you know that you know things that I don't know, because we've chosen different paths in life.

ANd y'know what? Whooooopty-doopty! C'est la vie! I like you anyway. I know that. YOu may not think that I really know this, but I do. I can't prove scientifically that I know that I like you, or even that I do like you. But I still do know it anyway. And I do still like you.

Y'know?    :-)
