The horse is wandering around my backyard.
He has no place to go.
He has lost all of his ambition.
Must be content with the status quo.

The sun has set on my backyard.
The horse never sleeps, it seems.
He doesn't suffer night terrors,
and doesn't dream bad dreams.

The sun has set on my backyard
The horse's mood is dark
He's missed his opportunities
and failed to make his mark.
