The narrator compares himself with three other boys who are about the same age and decorated with the same war medals. He reflects on the boys' changed attitudes once they discover how the narrator received his medal: WHY DO THEIR ATTITUDES CHANGE?

The text does not provide specific details on why their attitudes change. However, it may be inferred that their attitudes change upon discovering how the narrator received his medal due to reasons such as jealousy, surprise, admiration, or discontentment. The specific change in attitude would depend on the circumstances under which the narrator got his medal.

The change in the attitudes of the three boys towards the narrator is likely due to the way the narrator received his war medal. The narrator reflects on how the boys' attitudes change once they discover how he received his medal. It is possible that the boys initially admired and respected the narrator for his medals, assuming that he had earned them through acts of bravery or heroism in war.

However, upon learning the truth about how the narrator received his medal, their attitudes change. This suggests that the boys may have valued and respected medals that were earned through genuine acts of bravery or sacrifice. If the narrator received his medal through means that are considered less honorable or courageous, it could have diminished the boys' admiration and respect for him.

Additionally, the change in attitude may also be influenced by societal norms and values. Depending on the context and the culture in which the story is set, there may be specific expectations or ideals associated with earning war medals. If the narrator's actions or circumstances deviate from these expectations, it could result in a change in how the boys perceive him.

Overall, a change in the boys' attitudes towards the narrator is likely due to a combination of the way he received his medal and societal expectations surrounding the earning of war medals.
