Back in Kindergarten, my class used to have to bring in objects that were important to us for show-and-tell. Some kids brought sports trophies or souvenirs from vacation. But one time, a particularly popular kid got up in front of the class and subjected everyone to a painfully long presentation about his snow boots. It was nearing summer and there was nothing really interesting about the boots at all. Midway through the talk, it became clear—even to the rest of our six-year-old brains—that this kid nearly forgot about show-and-tell and just grabbed something on his way out of the house. But we all gave him a pass, even the teacher, mostly because he was cool and we didn’t want to get on his bad side.
