For Seth,

A jedi without a lightsaber
A dinosaur without teeth
A whale without a gun

These are all examples of feeling as if you have no use,
But what always happens when a jedi looses his lightsaber,
He finds it.

The Dinosaur,
His teeth will grow back.

And The Whale can always kill a shark
and steel his gun.

Any Way, The point is, No matter what you loose, you'll get it back,
But if you don't, Kill a shark to get it back.
