Oh, I see what you mean. From my experience, the methods are passed
down, not referred to from the parent. That is, Parent does have its
own critique method, not a reference to Grand_parent.critique(). So
when Child calls self.advise, it is calling its inherrited copy. Then,

Interesting. It has its own critique method? Hm. Not quite sure what
that means exactly...
Anyhow, I wasn't suggesting that Parent had a reference to
Grand_parent.critique(),

Since Child has no advice() method, it inherits the one for Parent.
Thus, Child can be thought of as being defined as follows:

. self.advise()
