[Mary Poppins] What *is* Mary Poppins? A benevolent witch? A guardian angel? A domesticated Fae?

I think she's a god. As in the New American Gods, where they are formed from a combination of belief and ritual. Mary Poppins is British. Like, *literally* the god of British. The rituals are cleanliness, respect, tea, and a reserved but sincere form of fun. 

She is basically the result of the collective consciousness of "Britishness" given humanoid form.
