Maybe there is a young boy as the protagonist, who is constantly trying to live up to the expectation of not crying. There could also be his family members or friends who either enforce or question this idea.
I'm not entirely sure as I haven't read it specifically. But it might be about the struggles and experiences of boys, perhaps related to society's expectations of masculinity and not showing vulnerability.
Well, 'boys don't cry' based on a true story is significant as it's a powerful portrayal of a person's fight for self - identity. In the story, the main character battles against society's norms and expectations. It makes us think about how we as a society define gender and the consequences when someone doesn't fit into those traditional definitions.
