‘If only the reader would play the scene with me, I’d do a better audition!’
A reader is there to facilitate the audition, not to play the scene with you.
Scene partners are your fellow actors in plays and movies or who you practice with in acting class.
The best readers will make sense of what they say, speak pretty quickly and lightly and leave most of the space in the room for you to occupy.
But they are not and should not be scene partners.
This needs to be learned so one more false expectation is given up and one more piece of disappointment goes away.
Learning this helps you get rid of false expectation, thereby alleviating disappointment.
Leaving a bit more room for your acting.
