Did the bride and groom learn about your phone lesson?
At the reception, apparently they did, as I've since learned.
I would never dream of profaning the Sacred, or interfering with someone's special day, and that didn't happen here, especially since by the time the musical presentations were over (they took about an hour) and the actual ceremony got underfoot, the ruders in the audience had gotten the message, and behaved.
As mentioned earlier, only three times during the hour-long ceremony did I have to lift my hand, indicating I was "reaching" for the handset, and no more than that.
I was seated up near the front, but way over to the side, all by myself, and behind the families of the bride and groom. They having not been present during the pre-nuptial concert, I was nothing to them.
During the service, some of those up ahead of me apparently had some sort of impression, some sort of gut instinct, "something" was going on, but as it seemed minor and harmless, they let it go, not bothering to look around to see what it was.
The "plan" had been to make a sort of show that would get me noticed by the rude person; nothing more than that. But that's not the way it worked out; it worked out even better than that.
The audience would see me make a slight movement, and then look around themselves to see who the rude person was. The rude person, suddenly having six or eight or twelve pairs of eyes gawking, would feel uncomfortable and put the thing away, and pay attention to the ceremony.
