I found this book in my children's hospital lobby and looked it over.
It was so fun and made me try for the reading time at my children's school someday.

At this time of year, I had often been asked from my children how Santa Clause could know what they wanted or how he saw who was nauty or nice.
I answered just a few of their questions quickly so that they were never satisfied, which caused me a kind of difficulty of raising them to be good.

But the book above gives me concrete answers to my children's questions!!
It's ME that enjoys it a lot!!!
Also I'm amazed how highly industrialized Santa's world is!
