A short term memory repository

There are ar least 100 billion galaxies in the universe. What we see of the cosmos when we look up at the night sky is essentially nothing, just a few thousand stars that lie near us in our corner of a single galaxy.

So, so you think you can tell
Heaven from Hell,
Blue skys from pain.
Can you tell a green field
From a cold steel rail?
A smile from a veil?
Do you think you can tell?

And did they get you to trade
Your heros for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange
A walk on part in the war
For a lead role in a cage?

How I wish, how I wish you were here.
We're just two lost souls
Swimming in a fish bowl,
Year after year,
Running over the same old ground.
What have we found?
The same old fears.
Wish you were here.
