I wonder why you did leave

Late at night when I cannot sleep 
When day is far and I do weep
When there is nothing left but to think,
I wonder why you did leave.

When I awake and start to feel
A void between us threatens to creep
It is my imagination or so it seems, 
I wonder why you did leave.

It is light and I cannot cry
But memories of us are rushing by
I walk about with a smile so deep,
And wonder why you did leave.

I ponder, I meditate, I reason, I grieve!
The only question unanswered still is why you did leave.
