Wish you were here - Pink Floyd

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?
And did they get you trade
your heroes for ghosts?
Hot ashes for trees?
Hot air for a cold 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.
