I’m totally sympathetic with your situation, and so sorry to know you have this hassle. Obviously, your mom’s, your, and others’ health are a top priority. I hope you all enjoy continued excellent health!
That said - and I don’t know whether you are in a position to do this - have you considered forgoing your discount as a goodwill donation to the theater community in their moment of crisis? I’m just thinking about the economic impact on the industry and all the actors, stage hands, and others it employs if theater lovers who might be in a position to help them survive this crisis only think of themselves. Imagine the impact of that on the industry if no one who could help does so.
It seems we all might take a long view and pitch in to the extent we are reasonably able to cushion the blow, and help support an institution and tradition we all love during this crisis. We all want to see it survive. I hope this won’t leave us with a world of only live streaming on our personal devices!
