The Greatest Happiness

“The greatest happiness,” said Valancy suddenly and distinctly, “is to sneeze when you want to.”
Everybody stared. Nobody felt it safe to say anything. Was Valancy trying to be funny? It was incredible. Mrs. Frederick, who had been breathing easier since the dinner had progressed so far without any outbreak on the part of Valancy began to tremble again. She deemed it the part of prudence to say nothing.

Aunt Alberta, to save dinner, plunged into an account of how a dog had bitten her recently. Uncle James, to back her up, asked where the dog had bitten her.
“Just a little below the Catholic church,” said Aunt Alberta. At that point Valancy laughed. Nobody else laughed. What was there to laugh at?
“Is that a vital part?” asked Valancy.
“What do you mean?” said bewildered Aunt Alberta, and Mrs. Frederick was almost driven to believe that she had served God all her years for naught.
