We don't "need" to discuss any of the subjects on this site. We do it because we like to.

That doesn't mean that our efforts are meaningless or lacking in importance by any stretch of the imagnation.

I don't need this thread, but I am sure I will derive great sustenance from it for my mind and my soul if it carries on.

I love the depth with which people commit themselves to discussions on this site. It is very rare that anyone posts rubbish.

I grow a little wiser with each visit.

I of course reserve the right to disagree with anything you say though.
