The narrator tells us that the reason why she doesn't like the shirt is because she knows that the man wants to go to an amusement park as soon as he's old enough. He's been trained to be a future heir to the company, which means that he has to play with the children at the amusement park. The narrator explains that she wanted to accompany the man to the park when he was young so that he wouldn't have to deal with his ego.
