How to know we know each other

Recently, I have exchanged two e-mail messages with the owner of a weblog which I happened to stumble upon. After the second message, he asked me: Do we know each other?

My first thought was: How should I know? But then, here is how to know we know each other:

If you think we could perhaps know each other chances are we do not.

If you think that I may ever say so you certainly do not know me.

If you think we might actually never get to know each other we already do (know quite an essential part of what I think we could possibly know from each other).

If you know that my middle name is Epimenides we in fact do know each other. But then, tell me, why do you ask?
