"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?

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"

-- Pink Floyd

Three years.
How I wish you were here.
