A spider lives its daily life, living through the edges, spinning its web, with precision. It waits for the moment, when the prey strikes the mesh, and lies still, calm and quiet, till the prey is unable to move anymore. It is waiting for the opportunity to strike, at the right time, at the point when the prey has given up, when the spider is sure, its victim has no escape. Thus are the rules of nature, one 'smart' outlives the other.
