On this basis, I think it's nonsense that schools are expected to welcome all children back but theatres must stay closed.
I get the close proximity thing but schools have basically been told to follow guidelines that absolutely won't work (SD with over 1000 children moving around a site regularly? Nah, SD won't happen...) It seems to be OK for 30+ children / teens to all breathe & talk in the same cramped space for hours every day but performers can't do it in a much larger space?
I have a lot of friends who work in theatre and they, quite frankly, are fucked. If we don't reopen theatres soon, there won't BE any theatres or people to work in them. Yes, it's a risk but seems to be that SD in any real sense has been abandoned by opening pubs, non-essential shops, etc. anyway.
