It was quick and painless and not as bad as you predicted. Now that you've been spared from suffering through it, put aside your surprise and start to take advantage of your good fortune. The universe gave you a break, now it's up to you to make sure that you don't find yourself in this situation again. Start putting things in place to ensure that history doesn't repeat itself.
A polite thank you, or a card, will leave a positive impression.
