How about this instead: an object's class is to the right of it in the 
diagram, and an object's superclass is above it.  The object 'a' is not 
a class, so it has no superclass and nothing appears above it in the 
diagram.  The object A's class is to it's right, i.e. Class, and A's 
superclass is above it, i.e. Parent.  Now what about Class?  It's a 
class because this works:

MyClass = Class.new

and because Class is a class, it is has to be an instance of Class.  So 
Class's *class* is Class, and as shown in the diagram Class's superclass 
is Module because Class inherits from Module.
