Signals you gave
Signals returned
Should tell us both
We haven't learned
Anything at all
From one another
From each other's point of view
Even though we might
Have understood a few
Still there's nothing
We can do
The harm has been done
Can't go back in time
To resolve what has come
Upon us both
Upon our lives

The signals were there

In retrospect
We were blinded by hope
Still it won't come back
The way things evolved
Cannot change the past
These things can't be solved
So take it as it is
Although we're in pain
Should have noticed these signs
These warnings should have gained
Some insight
In what we had
Too bad
We didn't understand
