The only thing that jumps to mind after reading your post is a children's story I've had since I was wee. Maurice Sendak's Nutshell Library is a collection of four little books.

Publisher: HarperCollins; Boxed edition 1962
ISBN: 0060255005
from the publisher---This 4-volume boxed set contains an alphabet book, a book of rhymes about each month, a counting book, and a cautionary tale all written and illustrated by Maurice Sendak. Includes the titles Alligators All Around, Chicken Soup with Rice, One Was Johnny, and Pierre.

My favourite story is Pierre : A Cautionary Tale in Five Chapters and a Prologue.

The prologue reads: There once was a boy named Pierre who only would say, "I don't care!" Read his story, my friend, for you'll find at the end that a suitable moral lies there.

Pierre has always been my mental companion when my depression gains the upper hand and "I don't care" is my response to just about everything.

btw.........not to spoil things but Pierre DOES end up caring.
