St. Peter said, "well, I think you could do it, but if you'd rather not, you could go to the "other" place and see if you like it!" So she said, yes, she'd like to visit Hades and see if things were any better for her there.
When she arrived in Hades, she was given a royal welcome, and shortly thereafter she was given her visiting teaching assignment. Only THREE sisters! She was very happy and thought she could visit all her ladies very easily. But, she asked Satan why she only had three sisters on her list when she was in Hades, but 100 when she was in heaven. He replied, "oh, we've got LOTS of visiting teachers here!"
