I suppose it could have been rehearsed more to get a smoother ‘flow.’
My overall impression
In the space of a simple theatre stage, people turn around and in a kind of kaleidoscope speak to someone in their lives—thanking them. They pretend for the moment we are their ‘other’ and so we have a mystery to solve. But then so do all the characters, who are not characters. They are themselves, the real actors who among other things recognize they are also characters.
