More than 40 years ago, my grandfather told me a parable about a turtle on its back on a fence post.
There are a lot of versions of this story, and thanks to the power of the Internet, you can look them up if you want too.
My grandfather's was different and it went like this:
Boy, if you see a turtle on his back on a fence post, think "What the hell? How'd that happen?", then take a second to imagine what the turtle is thinking.
He added. "And help the poor bastard down," but he was talking about the art of logical empathy. I'm not (although it is a good thing to learn).
I'm talking about a one-sentence acting class.
Your character is a turtle on its back on a fence post. As confusing as the situation is to you, the actor, your job is to imagine what the turtle is going through and act that.
