The static member still has to reside somewhere.  It isn't in limbo.  Static 
members reside in the class itself.  The class is like an object itself - it 
has member references and member methods, those marked 'static' in the class 
definition.

There is no "the object".  Static members reside in another object, the one 
representing the class itself.

Two different things, objects and references.

Objects referred to by instance members don't "reside in the object" either. 
A reference lives inside an object, either in an instance object or the class 
itself.  The reference points to another object or to 'null'.  The referenced 
object doesn't "reside in" anything but heap, conceptually.

Classes and instances don't have member objects.  They have member references. 
  References point to objects.  Objects don't "reside in" other objects. 
References do, sometimes, but not necessarily in instance objects.  The place 
from which a reference points and the place to which it points are two 
different things.
