The expresion ''every bird likes its nest'' meditates around a simple subject, the one that teaches people that no other place is better than home. Wherever you go the fact that it is not the place you have been living until than proves that nothing can destroy the feeling of being in your ''nest'', which you made with your own powers. The nest the birds make is a part of their lives. If a bird doesn't have a nest it doesn't have a place to leave and continue its life, so it happens to humans.
