Sister Mary Katherine entered the Monastery of Silence.
The Priest said, 'Sister, this is a silent monastery. You're welcome here as long as you like, but may not speak until directed to do so.'
Sister Mary Katherine lived in the monastery 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.'
'Sorry to hear that,' the Priest said, 'We'll 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, and the Priest assured her that the food would be better in the future.
On her 15th anniversary at the monastery, the Priest 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.'
