For how many people do you speak, Beadman?

I waste everybody´s time? With what? Telling you more than you need to know - that? With me trying to explain in some etail why it´s MOUARGHAD, not "MURACAD", as you think and said? And what point did I miss (again) in that poor third language of mine (I welcome you to discuss with me in German - heck, how much easier would that be, how much more precise could I be?!)?

What means "I could care less"? Don´t understand (!). Is that a saying?
