Peace - so many Churchill stories, so little agreement, I have no idea what he really said, I just love the rhythm of "arrant pedantry ... put." and couldn't resist sharing it. My second favorite Churchill story, after, "Yes, but in the morning I'll be sober."

Richard - there are many acceptable (and no "correct") responses to "Thank you." "Not at all" is certainly one of them, as are "You're welcome" and "My pleasure" and "Think nothing of it." Soon, "No problem" will also be "standard." (But it will never be "Received.")
