title: C++ : friends of class and "this" pointer
body: <p>I have one little question for you :), I understand that every method "secretly" gets "<strong>this</strong>" pointer of some class that they are inside but why that wont happen to "friend" functions ?
  Is it because they are NOT methods of class?</p>
  
  <p>Can anyone explain whole machinery, i am very interested in how "this" really works!</p>
  
  <p>thanks in advance! :)</p>
