就像电影结尾父母写给孩子们的信以及旁白里说的:
One day, when you're older,
you will learn all about the people we have befriended and the dangers we have faced. At times the world can seem an unfriendly and sinister place,
but believe us when we say that there is much more good in it than bad.
there's always something.
Something to invent, something to read, something to bite,
and something to do, to make a sanctuary, no matter how small.
