The second eats as much as is given to him, yet is always hungry.
The third goes away and never returns.

Two words, my answer is only two words.
To keep me, you must give me.

Sir, I bear a rhyme excelling
In mystic force and magic spelling
Celestial sprites elucidate
All my own striving can't relate

There is not wind enough to twirl
That one red leaf, nearest of its clan,
Which dances as often as dance it can.
