I walk down a corridor. Someone calls me back. I am supposed to come.

I sit next to F., dancers in front of us. F. asks me something, but I wasn't watching. Now the dancers are sitting in a semicircle. All in the same pose, on one side the dancer raises only her finger, the next one a little higher, and so on, until the last one on the other side raises her arm all the way up. It looks perfect.
