"What’s so bad about repetition?” the compulsion asks. But, no, really, what’s so bad about repetition? Or perhaps it would be better rephrased as: What’s so good about innovation?"
Surprise is delightful to the mind.
When the magician's prop fails to appear,
When a trumpet's blast we fail to hear.
When a poem's next rhyme simply falls flat.
That. That is the delight of surprise.
