Assembly Hall Dance Exercise (night of 04/05/2019)

In some kind of assembly hall of a school (and also something vaguely reminiscent of a shopping mall as well). Seated on a table. There is some kind of expressive dance exercise about to kick in - the kind of thing that kids may have had to do in Steiner schools in the 1970s. Everybody about to wave their arms about in an expressive way... The thought horrifies me. Will I be forced to join in? I say to someone at the next table that this kind of thing makes me feel very uncomfortable.
