Write a compare and contrast analysis of how "Broken Chain" and "Fish Cheeks" both address a common theme about belonging. I have 2 paragraphs and i need one more to put in the middle. here are my paragraphs: The Broken Chain and Fish Cheeks both share the same story, and that’s the story of belonging. Both these literary works have a theme of "belonging" in the sense that it is interpreted differently.In the Broken chain, people have to learn to love and appreciate other people, while in Fish Cheeks speaks about people who like their culture. In both stories, the physical appearance is very important fo the characters, as they are trying to change the looks to make people like them.

The characters want to change themselves n order to please people. However, the belonging will not happen if you change the physical looks. In these literary works, everyone has something in common, no matter how they look, and that everyone should be treated nicely. The person shouldn’t follow the rules blindly, because that way the person is losing himself and his integrity.
