Not clear to me what you see as the difference between tit for tat and give and take. In any event I question the distinction. I hang around because everything I think is accompanied by the realization that I could be wrong, even though I seldom think I am wrong. When I am wrong, I prefer to be told.

The truths you proclaim may reverse; the give and take you desire may not be what you imagine. For my part, I find a certain beauty to all this babble. Not to say I enjoy it all equally, only that I resist any attempt to close a history book.

My favorite posts are the screeds (yours included).
