I have to agree with you there! The whole kid in a candy shop, thrilled with the idea of not knowing what everything is for (and yet, realizing that anything that exists has some kind of story).... the whole adventurous spirit and the wonder!

And of course, the whole "bigger on the inside (or smaller on the outside)" thing. It stops everyone cold, except Wilf; he just noted that it could be cleaner on the inside!
