Wind in the Willows
Eileen knows this now to be a truly charming book but misheard the title to begin with, believing it to be Wind in the Pillows, an unpleasant bedtime affliction, guaranteed to do nothing to help a happy marriage.
The Lion, the Witch and the Wardrobe
Eileen knew this to be a classic book to begin with but sees the title as the three things you'd never want to lug around with you (and she'd fight two of them in any case).
Winnie the Pooh
After discovering this was not an insult thrown at Britain's greatest war time leader, Eileen enjoyed the book. Her heroine in it is Eeyore. She fully understands the down in the mouth scenario.
