It's amazing what can happen just by paying attention. This small but powerful book details the relationship between an old man who ran a cash register at a big-box store and a guy who worked at a college. The college guy wrote a letter to the corporate headquarters of the big-box store and extolled the old man's customer service virtues. That letter changed both of their lives and set the stage for a great friendship. More than that, the old man shared his simple philosophies of life and the university employee was smart enough to listen.
