Some thing is happening this weekend. Someone told us to expect some big thing. Somewhere in our city will be a flash mob. It is expected to form some times around noon. Some music will begin playing and someone will start to dance. Other people will join in the dancing someplace in the background.
Anyone can join in the dancing even if they don't know the dance steps. The grand finale will include anywheres between eighty and one hundred participants. One by one, the dancers will leave until there isn't someone on the floor. And anybody will pick up the boom box and walk away quietly as if nothing happened.
