The scene takes place in a Catholic church, with two little girls escaping the mass for a bit under the pretense of heading to the bathroom. It was actually a fun way to learn about for her. And having been raised catholic easy enough to explain.
Hardest part had to be the ending. The scene ends with a silly version of the Lord's Prayer and the characters ask for forgiveness of various trespasses. So how do you explain to a nine year old who Vanilla Ice was and why he is a trespass to be forgiven?
