In Tom Junod’s 1998 Esquire article, which is the introduction to the book by Fred Rogers, Junod discusses a little boy carrying a big sword. The little boy “[goes] into battle” against Mister Rogers. Mister Rogers whispers in the little boy’s ear. He later tells Junod, “’Oh, I just knew that whenever you see a little boy carrying something like that, it means that he wants to show people that he’s strong on the inside, too. And so that’s what I told him. I said, “Do you know that you're strong on the inside, too?” Maybe it was something he needed to hear’” (xxv – xxvi). Discuss this incident. What does it mean?
