All Beliefs are Welcome Here!
Mary Poppins used her power predominantly on objects that taught kids to sing, pick up their room, take their medicine, and have an 'all around sunny disposition'. For example, Mary Poppins taught kids to clean their rooms by causing their clothing items to dance around the room with them and allowing them to see that cleaning could be fun.
Nanny McPhee used her power predominantly on people (mainly kids) to teach a more strict version of the same lessons. For example, Nanny McPhee taught the kids to get up when they are told by giving them measles, forcing them to stay in bed, and making them eat nasty food and medicines.
In your opinion, which is the better teacher and why?
Which kids will retain the lessons?
