Orac: You are very perceptive; I have worried about too much all my life!! I thought I was asking a valid question, though. I mean, offending someone by using the wrong expression in a business letter is the sort of thing that can cost a company a lot of money!

But you're right, Orac, that there are other things about which I should worry less or not at all.
