What should you be able to say in the first session?
One repeating sequence: what starts it, what each of you does, how it ends, and what never gets repaired. Specifics beat slogans.
If you cannot yet say that sequence cleanly, that is the prep work — not more scrolling.
How do you prepare without rehearsing a trial?
Describe, do not prosecute. A private read at kionese.com can help you organize one situation so the first session starts higher.
