What good?

what good are the things that cannot do what they were born to?

What good is a wingless wren?
One who cant even fly.
All it does is sit
And stare at the sky.
It has great ambitions;
The greatest around!
But it tries to sing
And cannot make a sound.
What good is a songless sparrow?
Who can't carry a tune
Who oh, so often tries
To perform under the moon.
What good is a bird
Who holds everyone down
In its' desperate attempts to fly?
Nobody wants a useless bird.
So off it goes to die.
