From 8-year old Hilda’s diary:

The fourth commandment is a nice sensible one. God says that, “We Must Always Remember the Sabbath Day and Keep It Holy,” but that doesn’t mean that we have to go to church or synagogue or anywhere. We may do anything we want except work. Also no one in our homes must work and even the animals shouldn’t work. Some people make the Sabbath day on Saturday and some on Sunday and this is sensible too because some work really has to be done every day.
