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