It brought them together because they did not trust the monks or each other. In the story it says every one did not trust each other. The villagers and the monks made the stone soup and every  one was so happy .AND they gave the monks a place to stay because they made them happy villagers. THIS shows that now the villagers are happy and now they can be happy people. THIS reminds me of when my cousin always lied to me and one time he came over and gave me two presents he told me what they where but I did not believe him and when i opened them he was telling the truth and i said thank you 50 times and he spent the night and it was a wii and a xbox 360 and we played till night and I hugged my PS3 and we played it all night, just like the villagers celebrated all night.
