The World is Our Classroom!
In the most general sense, a classroom is wherever you may be engaged in the discovery and application of knowledge and ideas that are new to you. It may be a room with desk, chairs, and all of the other paraphenalia and people within it… a preconception we all likely share. However, a classroom can be many things: a park bench on a rainy evening, the back of a coffee shop, the top of an outcropping of ancient volcanic rock beside a rocky beach, a subway station in Paris (as Ezra discovered), a boat, an airplane, a dinner table, a shack beside the home built by our grandfathers where they sharpened their tools they used to accomplish everything we took for granted.
