When my best friend was much younger she used to believe that all newborn babies were created in a factory (she didn't know about sex or pregnancy at this age). She thought that somewhere in the world there was a massive warehouse full of newly created babies and that couples wanting a baby would have to go there and choose one to buy and take home. She thought that all of the newborn babies could talk and that they had to try and persuade couples to take them home instead of one of the other babies.
