Galadriel: Mithrandir, Why the halfling? Gandalf: I do not know. Saruman believes that it is only great power that can hold evil in check but that is not what I've found. I've found it is... the small things--everyday deeds of ordinary folk that keeps the darkness at bay--simple acts of kindness and love. Why Bilbo Baggins? Perhaps it is because I am afraid, and he gives me courage.
