    	You can't have it both ways.  If you want

myObj.greeting2 # No parentheses

    	To evaluate to a string (which it will if it's a property as you 
set it up), then it is necessarily true that myObj.greeting2(somearg) is 
going to try to call that string, which isn't going to work.  If you 
need to be able to pass in parameters, then you need greeting2 to be a 
real method, not a property, and you need to get the greeting string 
with

myObj.greeting2() # Parentheses

    	All this is as it should be.  The whole point of properties is that 
outside functions accessing them don't "know" that a getter function is 
called behind the scenes.
