In reacting to their comments we tried to adopt the attitude of the Churchill
quotation below, although at times we felt more like the Mark Twain quotation.

"Criticism may not be agreeable, but it is necessary. It fulfills the same function as
pain in the human body. It calls attention to an unhealthy state of things."
--- Sir Winston Churchill

"I like criticism, but it must be my way."
--- Mark Twain (Chapters from My Autobiography)
