Guest, I promised you I would read the whole of this thread and then come back to you, and I have.
I like what you say. You say things that I know but you say things differently so that they seem new. Because your new way of saying things is unfamiliar, it makes me think, and that is good.
Because I have now read every post on this thread I have got to know some of the people here much better than I would otherwise have done, so that when I see them on other threads I can understand much better what is going on.
A lot of it is not what I expected to find on this forum, but I can now see what is happening.
Thank you, Guest, and several others whose names I don't remember just now.
