Thank you to Rick Scheffert for the suggestion!
"I would like to share what I did with "No Witnesses." Instead of using it as a monologue I split it up between two people. It was really quite effective. I got comments from audience members about it.
On stage the two characters were unaware of the other person. It went as follows.
Actor 1: I saw it... This terrible thing.
Actor 2: It happened to this girl I don't even like. And no one knows who did it...
Both: Except me. (Pause) Do I tell?
Actor 1: It's between what is right and what will ruin your life.
Actor 2: I don't even like her...
Actor 1: She brings it on herself.
Actor 2: Why does she have to be so... Weird?
Actor 1: And if I tell... Everyone will turn against me...
Actor 2: I will be like her... An outcast...
Both: Invisible.
Actor 1: Is that how it happens... One little thing you do turns you in to a leper?
Both: Social leprosy.
Actor 2: The right thing feels so wrong.
Actor 1: I know I'm supposed to tell the truth but the truth will not set me free.
Actor 2: The truth will ruin me...
Actor 1: Keeping quiet will ruin her...
Actor 1: And I don't know if I care.
Actor 2: And I don't know if I care. (actor 2 needs to be careful not to sound like they are agreeing with actor 1 as they are supposed to be unaware of each other)
Actor 2: I guess that's what happened to all those guys who stood up for what was right...
Actor 1: Gandhi shot, Martin Luther King shot, Jesus crucified...
Both: I'm no Jesus.
Actor 2: I wonder if she could ever forgive me?
Actor 1: She can get over it right?
Both: (not quite in unison) Forgive me... I don't want to be crucified.
