   You know, I've let this sit for a while to see if I can bring myself   
   to overlook you being an arrogant, ill-mannered little prick.  I   
   can't.  How's this for simple words?  You can sit on your thumbs and   
   whistle for an answer, even though the answer is pretty obvious if   
   only you weren't such a thickie.  My experience with people in the   
   sci.physics group is that most of them are ill-mannered little shits.   
   Or perhaps that's just those who crosspost over here.  In any case,   
   you are no exception.

   Pull your head out of your ass and think about it.

   If you don't want to be presented with a bill, don't tell people what   
   they must provide you with.  And learn some manners.  Beggars can't be   
   choosers and you're the beggar here.  I choose to tell you to pound   
   sand.

   You think I'm somehow stopping other people from answering you?   
   Paranoid much?  If I could do that, at this point I would purely   
   because of the size of the stick up your ass.  But other people are   
   welcome to do what they want.  As I said, the answer is obvious if   
   only you weren't quite such a thickie.

   I find you quite 'curious' as well; a guy who doesn't know the answers   
   but thinks he can get them by being a rude little asshat.   
      
      
   --   
   You are   
   What you do   
   When it counts.
