SISTER DOROTHY

One morning Sister Dorothy woke up, got dressed and made her way to   breakfast. As she walked, she encountered Sister Agnes, who greeted her   with, "Good morning, Sister Dorothy. I see you've gotten up on the wrong side of the bed this morning."
 
Puzzled, Sister Dorothy said good morning and continued on her way. Then  Sister Elizabeth saw her and said, "Good morning, Sister. I see you've gotten up on the wrong side of the bed this morning."
 
Even more puzzled, Sister Dorothy said good morning and kept on walking.
Finally, Sister Anne approached her with a good morning. Sister Dorothy asked, "Are you going to tell me I've gotten up on the wrong side of the bed this morning?"
 
Sister Anne said, "No, no, I wasn't going to say that, I was just going to mention that you're wearing the bishop's shoes."
