KIngSpeed, I totally understand. I do. But for everyone who feels as you do, there's someone else who would say that they didn't come to see BP break character and stop the performance. Things can go both ways with this.
Yes -- but in my opinion, if the audience has already been taken out of a performance by a cell phone ringing or a child screaming, the actor(s) might as well stop the show until the disturbance is silenced, and then pick up where they left off or just before the spot where they left off.
