My dear Wormwood...

As an English teacher, it's difficult to pick a "favorite" book. Or I guess a more accurate statement would be: "As a nerd, it's difficult to pick a "favorite" book."

BUT if we're referring to a book that I could read once a year and still uncover precious truths, then C.S. Lewis' Screwtape Letters is a good example.

Here's an excerpt from Screwtape's letter to Wormwood about the Real Pleasure of reading:

"And now for your blunders. On your own showing you first of all allowed the patient to read a book he really enjoyed, because he enjoyed it and not in order to make clever remarks about it to his new friends. In the second place you allowed him to walk down to the old mill and have tea there--a walk through country he really likes, and taken alone. In other words you allowed him two real positive Pleasures. How can you have failed to see that a real pleasure was the last thing you ought to have let him meet? Didn't you foresee that it would just kill by contrast all the trumpery which you have been so laboriously teaching him to value? And that the sort of pleasure which the book and the walk gave him was the most dangerous of all? That it would peel off from his sensibility the kind of crust you have been forming on it, and make him feel that he was coming home, recovering himself?"
