Why do YOU think Bilbo returns to the dwarves instead of staying with the elves? What does this choice say about Bilbo? Do YOU think it was the right choice? Why/why not?

Bilbo was part of their team. He was loyal to Thorin and the other dwarves even though they were often hard on him. This shows Bilbo to be a Hobbit of his word. It shows Bilbo's sense of loyalty an courage. I'm not sure what you think about this though.
