Ghost of a Ghost

I guess we didn't notice.
Maybe.
I think I did.
When I was young.
I knew.
I saw the ghost.
Hiding in my mirror.
But I didn't realize who he was.
The little boy who walked with me.
Calling me a name I didn't recognize.
I know the name now.
But I had forgotten the boy.
For many years he hid.
Masquerading in dresses and skirts.
And I know him now.
I know who he always was,
But isn't yet.
I don't recognize
the little girl that stares at me anymore.
