A chaque oiseaux son nid est beau.
Idiomatic translation: The bird loves her own nest.
Meaning: If we were to grade ourselves, the grade would virtually always be very good; We most often vastly overestimate ourselves.
Strauss, Emanuel (1994)
Warm Bodies is actually like a metaphorical message for those who are dead inside and that there is always hope to be alive again and if you connect to this movie you’ll understand it in a whole other level.
At some point, it’s also about fueling our strength and will to change from our past, letting it go, and move on; make new memories, and even go as far as adapting to a completely new identity.
