At the beginning the villagers didn't trust each other because they had Famine, floods,and war. At the end they trust each other because they made Stone Soup. 

 In the story when  the monk's came they went to knock on doors nobody answer the door because they didn't trust each other. Also in the story a brave little girl went home and got her mom's biggest pot. Also in the story when  the Stone Soup smoke drifted, every one came out to see what Stone Soup was.

 This shows that the villagers is starting to trust each other again.

This remind me of when I never trust my sister holding my stuff because she try to give it to some one that i don't know or she put it on the floor and leave. Then after my mom told me start to trust my sister again.Then I trust my sister again. Just like the villagers started to trust each other again.
