Exactly! I have had people call National Storytelling Day silly. I guess if you think of it as a celebration or holiday, probably... but, I think it is a great tool for teachers.
I also agree that storytelling was the only means of communicating history, passing it down from generation to generation. When I was growing up, a lot of the family history was passed on this way. Who wanted some of that written down???
It is definitely a good day for storytelling.
