Yes, to me the idea of double booking means to have more than one partly read book stacked up on a table nearby so whenever I finish all those books I started to read, I have double and more books ready if I ever get around to doing that. However, for accountants double booking is a different thing, especially when the other set of books is going out of the office and into the hands of some other outside people who really does not belong to the organization itself and is just champing at the bit for opportunities to criticize the finer points of finance. I really don't understand what that was about. You could always ask my mother.
