my dear father twilight

I remember once I asked
Why your hair was grey
You said it was silver
And that you were father time
Upon which you told me the story
Of father twilight and how he prepares
The earth for nighttime to be greated
In the morning by the sun child
I never once thought you were telling
Me the story of how you would die
And now my opah is dead
My dear father twilight
May the lord watch
Between me and thee
While we are absent
One from another.
