In the Mormon Church, you don't clap during the services. None of those loud acknowledgements such as "alleluias" or "Amens," either. No. When someone performs a lovely musical number, we are merely moved to tears or smiles of admiration. Total silence rules until after the service when we rush up and hug the person or pat them on the back and congratulate them on their superior peformance.
Except, that is, for when our baby was just two. Her daddy stood and in his very impressive bass sang a piece from "The Messiah." It was magnificent. Few people are aware of his fine talent and there were audible gasps. At this point, Baby yelled, "Yea!" and clapped her heart out. That was one Mormon performance that got its just rewards!
