I began to investigate "play." I wanted to see how play was formed; how necessary it was. I began with my own memories of playing. I decided to set up situations, and I found friends to act in my scenes who would enjoy themselves, and who would be natural.
I noticed something other than mere playing, though I was just watching friends engage in ordinary activities: a conscious effort. I uncovered unexpected motives while recording these people. I raised questions concerning it and included these interpretations in my story.
