Lisa, my co-worker at the travel agency, needed to send a letter of apology to a customer whose trip was a complete fiasco from start to finish. I reminded her of a similar situation a year earlier and dug out the letter I'd written then.
"All you have to do," I told her, "is to change the details, the date, and the name."
She looked it over and smiled wryly. "We won't even need to change the name."
