Wish you were here

As you all know, this creation is not mine, but i want you to ponder over the meaning of lines and think...what are we doing, why are we doing, whatever we're doing.

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

Did they get you to trade
Your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
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.

Wishing you all were here with me.....but I am Here Without You
