Pairs stand facing each other.
They close their eyes and synch breathing.
They check in with themselves - this can be led by the teacher in a kind of guided meditation.
Once they are centred, they open their eyes and look at each other.
They realise how they feel about the other person - that feeling is innate - a mix of how they are feeling and what their senses tell them that the other person is feeling.
They then do an alternating three line scene - the "script" of the scene is:
1st line must start with I 2nd line must start with you 3rd line must start with we
Then the scene is over.
The idea of this is that you can find everything you need for a scene from within yourself or from your scene partner. All you need to do is listen to what is in front of you.
These scenes can take a lot out of a person and you should build in time to recuperate.
You can obviously set up a scene this way and then abandon the script too.
