And it is your coat.
But it is not your closet.
You keep too many old hats in there.
You keep a dead cat in there.
There is a strange dead cat in not your closet.
But it is not dead.
It is alive.  And you should not be keeping it in your closet.
Let it go. 
Let the poor cat go.
Free the cat.
Let the cat escape.
It's a good cat.  Doesn't it deserve its freedom?
You have a strange coat in your closet.
You still have a strange coat in your closet.
O coat in my closet that is not mine.
You, coat, have been my stranger for years and
I didn't recognize you, I failed to know you, coat.
I have failed many other stranger things.
