Our performance for you this evening has come to an end. However, we have a relationship with our friends in the press. Agreement is this, that if they do not interrupt the performance with photography, at the end we will present (for our friends in the press) a non-performance, during which they are free to take photographs. So this will nay be a non-performance: since it's not a performance, if you don't want to be here - you may.
