Common courtesy goes a long way, and you do not have to admit wrong doing in order to be courteous.
Bingo. All too often, we have the idea that protecting our rights requires being offensive. The simple fact is that being courteous while not volunteering anything you may have done wrong in this or any other life goes a lot further to protecting your interests than taking a position that will make your attorney squirm like "and then I told him I wouldn't speak further." And if you act like you've got something to hide, you are much more likely to need said attorney.
