Built to Spill traces

Daylight cannot really hide what's alive
I know it's hard sometimes
For you to tell where you end
And where the world begins
You do your best to avoid assimilation
Guess that's the best you can do
And though the parts of it that matter change
All traces disintegrate
At night my mind gets on this train of thought
And can't get back off and when you know
How few things there are worth knowing
I suppose anyone who tries could forget
Responding now to trains that crash before you
Never thought crashing could happen to you
And though the parts of it that matter change
All traces disintegrate
