I've been through VV1 and VV2 several times. I think I'm on like my 10th or 11th tribe in VV2, though the only one I've saved is my very first one. One thing continues to baffle me about VV2.

Background: When you drop an adult near a child, the adult will either tell a story or teach the children. The children will either squat to listen to the story or they will line up to attend lessons. I prefer the teaching/lessons result because all of the children (well, most anyway) come running in that case.

Question: What's required for a villager to be a teacher as opposed to a storyteller? I had suspected that only master scientists or master doctors could teach. Then I realized that the villager needed some parenting skills to teach. None of it seems to be consistent, though. Does anyone know the specific formula? Or is it random?
