What Are The Things You Cannot Know

I'm wondering if anyone knows the author of this poem.

What Are The Things You Cannot Know

What are the things you cannot know,
the moods and shades I cannot show,
the many nuances of self,
which gather dust upon the shelf?

The smiles paraded for the world,
those frequent faces I unfurl,
the wrappings of a private me
I do not want the world to see.

Can you know my secret fears,
the shames I've suffered through the years,
the things I am when I'm alone,
safe inside my little home?

How I look when first I wake,
or all the liberties I take,
could you stand me if you knew,
all the dreadful things I do?

I'd love to be an open book,
all before you when you look,
nothing kept in privacy,
A human singularity.

To never have to falsify,
the secrets of the self I hide,
but let us face reality,
you wouldn't like the real me.

So as always I shall dance,
smiling with resilience.
Staged in my publicity
Nothing but a mime of me

Confidence and blasphemy,
conceal my actuality,
safe behind a painted face
of dignity and awkward grace.

And snail-like I struggle on,
my solitude and darkness one.
Quick to curl inside my shell,
if you try to know me well.

There I shut out all the light,
blinker and conceal my sight,
I might be me, but how to know,
when it's always someone else I show?

I can tell you for a clear and honest truth
I did not write this poem
