Back again

Is there more than one of you?
Of course there's not; it isn't true.
But the name is yours, and his words
remind me of the warbling birds.
So much like you in many ways--
reminding me of early days
when you would write so many things
about yourself to me;
How long ago it seems,
but now you're back again.
Not really,
though for all the world
you remind me of him.
No, that isn't true.
He reminds me of you.
