The unfinished and unsent letter of apology found in your desk shortly after we buried you.

It was, you were right, a sparrow's song.
Of course I knew you'd been gone for years
where did you go?  
I had, as you know, gone nowhere
or rather went with me wherever I went but you
you left us both.  
I will likely never forgive you 
or myself.
I'm sorry. Please come home.
