Your son is so funny! I would be charmed to receive such a note. I love Calvin and Hobbes and forgot about them. I'll have to dig them out for DS4. I think there's a part when he learns there's not santy claus, i'll have to hide that one for awhile. DS4 is in that in between not quite sure phase with magic stuff. My mom was playing a game with him where they built castles with moon sand, and she was hiding some small trinket in it without DS seeing. I think he truly believed the moon sand was magic! Even though they were his own toys, he would say, "look! now i have another one of these!"
