Every Broadway show will eventually close. There were over 7000 performances of “Cats” but even this theatrical tour de force ended after it’s producers felt it was no longer pertinent or popular.
All of us have long running shows in our minds. They may be “Mom never loved me” or “I’m not smart/strong/good-looking enough.” These are the shows that often play for many years after they’re no longer relevant. Their time has passed so we need to “close them down.”
If a show only has one audience member it must not be that good. Don’t be the last person to attend. Learn when to close the show and move on with your life.
