Not so different from what happens when Mudcatters get together. We call each other by our Mudcat names and by our real names interchangeably.
Living is the business of being alone, when you get right down to it. No one can know you as you do nor can you know someone as they know themselves. That is true both in your most private moments and in the public face you present.
And frankly, I think that is OK. I'm frequently alone, rarely lonely. I think the distinction is to be made in ourselves, by ourselves.
