Here we are in agreement.

Everything in a computer program is an abstraction, and of course you can arrange these abstractions however you like. You could create an instance of a Square that inherits from Paper and has dimensions of "A8". I'm merely arguing that when building an object whose shape may change, using a PastryDough class is probably preferable to using one called Square.
