Well, from this story, perhaps it tells us that little boys need to be more assertive. In many situations, if they are too modest, they may not get the recognition they deserve. For example, in a school setting, if a boy is too modest about his academic achievements, teachers might not be fully aware of his capabilities and he could miss out on advanced study opportunities or awards. So, it's important for them to balance modesty with self - promotion.
The 'little boys shouldn't be so modest story' likely imparts the idea that boys should not shy away from presenting their skills and talents. It could be about how in a world full of competition, if little boys are overly modest, they might be overlooked. Let's say in a sports team selection. A boy who is very good at a sport but is too modest to show his skills might not be picked for the team. Whereas if he was a bit more confident and showed what he could do, he would have a better chance. Also, it might teach them that self - confidence can lead to personal growth and development.
We can learn that boys should be confident. Modesty is good, but excessive modesty might hold them back from showing their true abilities and seizing opportunities.
