Big Fish, Small Fish

Big fish, small fish
If you were born in the aquarium,
Bred in the aquarium
And by the aquarium, your final omen,
Would you have ever known the ocean?

If your life was a glorified fishbowl effect,
And your curtains have scarcely ever met,
Within closed doors, what would you do?
 Would you know to sing a song or two?

If the fluorescent light begins to fade,
And your focus shifts from the man-made,
Would you be able to take in the sun?
Or is this a battle the system has won?
