A word needs a voice.
A voice needs a speaker.
A speaker needs a message.
A message needs a messenger.

The boy's birthday was the day before,
And he was grateful for his gift.
So he expressed his thanks in a letter.
The message needed a messenger.

The politician signed a bill,
And was grateful for his bribe.
So he expressed his thanks in a letter.
The message needed a messenger.

The lover looked up at the clouds,
And was grateful for his love.
So he expressed his thanks in a letter.
The message needed a messenger.

And so the messenger passed the information on,
Like neurons in the brain.
From the objective view of the messenger,
It was all insane.
