I do these two games, in one (The First Thing) i open my eyes and say the first thing that comes into my head about the person sat in front of me, in the other (Your Turn) they have a minute to say whatever they want to me.
It really struck me that the very first thing that comes into my head is often banal, or even offensive, and that somehow they are a simplification or a reduction of the person.
This was re-enforced by people saying amazing things to me in the second game, who if they had come to The First Thing would have probably met with a fairly bland response.
