"You and I" by Mary Ann Hoberman

Only one I in the whole wide world

And millions and millions of you,

But every you is an I to itself

And I am a you to you, too!

But if I am a you and you are an I

And the opposite also is true,

It makes us both the same somehow

Yet splits us each in two.

It's more and more mysterious,

The more I think it through:

Every you everywhere in the world is an I;

Every I in the world is a you!
