butterflies have coloration to make them look like something not so tasty. sharks sneak up on their prey. baby deers are made to hide in the woods because they are vulnerable. humans arent exactly hunting or being hunted but ya know, my instincts still tell me to not just let everything hang out in the open. my heart is vulnerable. i don't need to allow others to eat me alive.. turtles bury their eggs, coocoos put their eggs in other birds nests. ya do what ya gotta do.
