It’s not a bag of magic beans; I think it is mostly John’s stock speech with a preface about how we all trust and love each other and are there to give each other as much fun as possible, which segues into the safety tools – for tabletop I use “The Door is Always Open” (you can get up and leave whenever you want, no questions asked, please take care of yourself) and the X-card, which I try hard to model early in the session to normalize its use.
During and after my speech I check in with everybody and make eye contact to make sure we are all on board.
