If They Knew

People all look,
But none of them see.
First glance is all they need,
So none of them know me.

Make another joke,
Bout a slit wrist,
When they have no clue,
Not even the general gist.

No-one knows who I am,
Just accept my transparent act,
As though it were convincing,
A real solid fact.

Would it scare them,
If I told the truth?
Everything about me?
All about my youth?

If they knew my dreams,
If they knew my nightmare,
If they knew me,
Would any of them care?
