I go to a dance class and we do dance displays at local events sometimes . We wear our signature black t shirts and black jeans. Today we are meant to be doing a display for over an hour at an event . There’s no shade and we are meant to wear our usual outfit of jeans and black t shirts. No marquee , no huge gazebo. There’s a lot of older people meant to be going.it’s a diverse mix. I think it’s irresponsible to expect anyone to dance for that long in this heat. Might add we kick off at 12 30 - the hottest part of the day. The teachers seem to think it’s just business as usual and are looking forward to seeing us all there. Just seen here in the midlands is meant to be one of the hottest areas today ! I think we will all pass out !
