From 8-year old Hilda’s diary:

Today I asked Grandfather if I could worship Ito’s God besides my own and he said that it was probably a good idea to have two Gods, just in case one was busy when you needed him, the other might be free to help. Like the night I wanted to take the spot out of my dress. But then he got serious and said that, “No! You certainly can’t have another God, not anyone else’s God, and if you are a good girl, God will hear your prayers and answer them in his way.” So I guess I can’t have Ito’s God. I am sorry, as I was going to ask him for curly hair. I just thought he might be one who would do this. Maybe I’ll ask Ito to ask him for me, but if Ito prays for me it is not like me praying, and then neither my God or Grandfather could be angry. I will ask Ito tomorrow.
