We flipped a coin to decide which direction to go. When we got to the end of a block we flipped a coin to again decide whether to take a bus or walk. On the bus we flipped a coin to determine which stop we got off at.
This process continued all day. We would decide whether to enter a store by flipping a coin. We alternated flipping the coin. Often deciding how long to do something and when to start or leave something else based on the coin flip.
This process took us to neighborhoods of the city, San Francisco, that we had never been to before. By the time night fell, we had met half a dozen people from jobs and backgrounds that we would never have met under any other circumstances.
By this coin flipping process for decision-making we had entered a completely different world. A world adjacent to our world but completely different.
I only did this once. The experience was so complete and overwhelming I only needed to know what it was about. It was a new world I was not prepared to live in.
