So far in the game, I don't understand some of my villagers' behaviour :

1) Secretly practicing a dance?
2) Complaining to "thin air"?
3) Drinking rain?!

SO the kids can only attend lectures every 24 hours, will their skills only improve if I tick the skill box?

What is the significance of adults attending lectures as well?

So I've solved Puzzle 5 now, are there anymore dances? Is it important in the game to make it rain - will it trigger something?

How come my chief doesn't point out things like the others are mentioning - like pointing out rare collectibles or mushrooms?

Thanks for all your answers/suggestions
