Have you played it? It is really intense. It requires a lot of trust and openness. To answer the questions honestly, involves a high degree of opening oneself up to vulnerability. If this game is going to be played, I think there needs to be some sort of preparation for folks ahead of time. I'm not sure how though. But really, the game is uber-intense. It also involves a lot of concepts that are alien to lots of folks. If you already are into all that kind of stuff, than it works great, but if you aren't... well, let's just say that I went to Cafe Gratitude with a bunch of friends of mine, and few of us were able to take the game seriously at all. I was, but I'm into that kinda stuff.

So I'm not sure how to solve this potential problem, but if you are planning on doing this activity, be sure to at least play the game yourself ahead of time, and try and conceive of potential problems and solutions.
Thanks again for all your hard work!
