What happened?

I haven't seen your face
At all these past few years
Such a change from the times
You were always near

The end, it came so quickly
No one ever knew
What really drove you to it
Was there something we could do?

Then again, perhaps thats wrong
We'd already done too much
Gone was all we once had
The times, way out of touch

Although we can't go back
Since you're here no more
Forgiveness ends the matter
Closing past times' gaping door
