We, the water people, have this habit of hiding behind walls.  We do this for comfort, reassurance, security.  But all we are truly doing is separating ourselves from others, creating a bubble around ourselves.  Reassurance? Comfort? Security? How about solitude.  That's all it really is.  We fear being hurt, and so we never get close to people.  What a lonely life.  We play everything safe, never chasing wild dreams, in fact most the time we scold ourselves for dreaming such dreams.
