I know you

I know a man like you
so hard and calloused
broken with years of harsh labour
shedding tears but never revealing their meaning

I know a woman like you full of laughter
always happy
sometimes worried
looking into a glass sphere and seeing me inside

I know people like you
a common lot
nothing special
always surrounding me

You can be categorized and labeled
I will know you now
I have known you forever
there are people like you everywhere

But where am I?
Who am I?
I am unknowable
uncategorizable

I am free
