Nobody turns so quickly into a bore as a traveler home from his travels. He enjoyed his trip so much that he wants to tell us all about it – and “all” is what we don’t want to hear. We only want to hear some. What made his trip different from everybody else’s? What can he tell us that we don’t already know? We don’t want him to describe every ride at Disneyland, or tell us that the Grand Canyon is awesome, or that Venice has canals. If one of the rides at Disneyland got stuck, if somebody fell into the awesome Grand Canyon, that would be worth hearing about.
