As she passed the young novices...

[Bad Karma]

As she passed the young novices, Mother Superior said, "Good morning, ladies," and the novices replied, "Good morning, Mother Superior. May God be with you."
But once they were past, she heard one novice say to another, "She got up on the wrong side of the bed this morning."
Mother Superior was surprised, but decided not to pursue it.
Soon she passed two sisters who had taught there for years. They exchanged pleasantries, but again she heard them whisper, "She got up on the wrong side of the bed this morning."
She wondered if she had been harsh with them and vowed to be more pleasant.
Down the hall came retired Sister Mary. They exchanged greetings but Sister Mary added right to her face, "Looks like you got up on the wrong side of the bed this morning."
Mother Superior was floored. "Sister Mary, what have I done wrong? Three times this morning someone has said that about me."
Sister Mary looked Mother Superior in the eye. "Oh dear, don't take it personally. It's just that you're wearing Father Murphy's slippers!"
