‘Come in, come in and take a seat, but please don’t wait for the show to start.
It has already started.
You probably thought it would begin once an audience had assembled, we apologize for any confusion.
The show began before you arrived and it will continue after you leave.
(It may follow you like a puppy or a lingering dream.)
You don’t have to stay here, this is just where we keep the chairs and you can take your chair with you, if you are attached to it, or you may choose another.’
