""Don T, I haven't confused the two of you, to my knowledge.""

Then I'll spell it out so your knowledge will be slightly more up to date.

When you post one of your interminable screeds responding to one of us, and you simply refer to "Don", the reader may have to trawl through a dozen posts from both of us, to make sense of it.

When you respond to both of us in separate paragraphs of the same post, it becomes even more confusing.

Your posts are incomprehensible enough without that added difficulty, and even I, (and, I suspect, Don F) have difficulty in sorting out which of us is referred to, when returning from doing other things.

Don T.
