What is a lesson that Danny learns from Reuven?

And, please answer soon! I have an essay due tomorrow for this and this question is mandatory!

Apparently no one has answered your question yet because your extra appeal made it look like someone had answered it. I'll try to help--I hope its not too late.

I think that Reuven teaches Danny something about what is happening in the world outside of their enclaves in Brooklyn. Reuven helps Danny understand that he needs to separate from his father and develop his own undestanding of the world. As much as Danny feels loyalty to his father, the bond of friendship with Reuven helps him to learn that there is more than one way to study the Tallmud and more than one way to find one's place in the world.

Danny learns restraint and introspection from Reuven.
