It's funny you mention it; I have a friend who writes books who had trouble with McCarthy and I recently mentioned this same criticism. I suggested ATPH to her and this same character came to mind as a decent piece of work on that subject.

I will say this about the passage tho: McCarthy writes a small narrative which does seem to explain her choices and character as it affects John Grady. It's convincing, and she's a good character, but even there she's something of a set piece.

Still, glad you mentioned this. Thanks.
