Sister Mary Katherine entered the Convent of Silence.
The Priest said, "Sister, this is a silent convent. You are welcome here as long as you like, but you may not speak until directed to do so."
Sister Mary Katherine lived in the convent for 5 years before the Priest said to her, "Sister Mary Katherine, you have been here for 5 years. You may speak two words."
Sister Mary Katherine said, "Hard Bed."
"I'm sorry to hear that," the Priest said, "We will get you a better bed."
After another 5 years, Sister Mary Katherine was summoned by the Priest. "You may say another two words, Sister Mary Katherine."
"Cold food," said Sister Mary Katherine.
The Priest assured her that the food would be better in the future.
On her 15th anniversary at the convent, the Priest again called Sister Mary Katherine into his office.
"You may say two words today."
"I quit," said Sister Mary Katherine. "It's probably best," said the Priest,
"You've done nothing but bitch since you got here."
