Wish you Were Here- Pink Floyd :'(

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.

This song is able to make me cry every time :'(
