In theory, this play is all about that concept. In practice, I struggled at times to link this social comedy with the theory.
Without the futile search for intellectual insight, it was a reasonably fun evening at the theatre but a rather lightweight one. A super cast for this revival, but I’m not sure this play is worthy of a revival within 20 years, even though the world has/had changed between times.
Here is a link to a search term that finds plenty of reviews, mostly indifferent ones. The consensus seemed to be that the production was excellent but the play somewhat lacking. Although neither Janie nor I had seen the play first time around, we thought that assessment was right.
