There is a dialogue of the film ‘The Hobbit-An Unexpected Journey’, which i would like to quote:-

“Mithrandir? “

“Why the Halfling?

” I do not know. Saruman believes that only great power can keep evil in check. But that is not what i have found. I have found that it is the small things ordinary people do in their everyday lives that that keeps the darkness at bay. Small acts of kindness and love. Why Bilbo Baggins?… Perhaps it is because I am afraid… and he gives me courage….”

A must watch film..if you are interested in words and fantasies.
