Wish You Were Here by Pink Floyd

I sang this song all day on 9/11 without thinking why. Later the lyrics came to attach themselves to my messy feelings about experiencing the day and those since:

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.
