Mark a story that interests you. You are seated with people in other countries who marked the same one, and each of you writes your own account before any of you reads a word of anyone else’s.
Pick a party of two or a party of four. Always different countries. Nobody reads until everybody has written.
A board of stories is open. If one interests you, mark it. Nobody sees who else has.
You are seated at the party you picked, a party of two or a party of four, everyone in a different country. Each of you writes your own account before any of you can read a word of anyone else’s. This takes a day or two, because writing does.
When the last person files, all of it arrives at once. Three sentences is a complete answer. Nobody was influenced, because nobody had seen anything.
Each person at the table answers one other, so nobody writes into a room. That is where it ends.
