When someone gives us something that has a huge potential benefit—and costs us absolutely nothing—what should we say to such a fine person? “Thank you!”I landed in New York feeling lonely, guilty, and ashamed of myself. I immediately called Lyda and told her my cost-benefit story. I assured her: “The next time you help me with my driving, I am just going to say, ‘Thank you.’”“Sure you will,” she said with a laugh (sarcasm free of charge). For some reason, she seemed to doubt that I had undergone a true religious conversion.“Just you wait. I am going to do better.” I continued.“We’ll see.” she replied.
