As Haw enjoyed the New Cheese, he reflected on what he had learned...
He realized that when he had been afraid to change he had been holding on to the illusion of Old Cheese that was no longer there. So what made him change? Was it the fear of starving to death? Haw smiled as he thought it certainly helped.
Then he laughed and realized that he had started to change as soon as he had learned to laugh at himself and at what he had been doing wrong. He realized the fasted way to change is to laugh at your own folly - then you can quikly let go and quickly move on.
He knew he had learned something useful about moving on from his mice friends, Sniff and Surry. They kept life simple. They didn't overanalyze or overcomplicate things. When the situation changed and the Cheese had been moved, they changed and moved with the Cheese. He would remember that.
He also used his wonderful brain to do what Littlepople do better than mice. He envisioned himself - in realistic detail - finding something better - much better. He reflected on the mistakes he had made in the past and used them to plan for his future. He knew that you could learn to deal with change.
