Dear Sage, It was my turn to review you last night for your Science exam. Our review went something like this:
Me: Can a non-living object without an engine move by itself?
Me: is wind a force?
Me: is your book living or non-living
Me: What outside forces can move the pages of your book?
Sage: Humans, wind, running water if I drop it in the river...
Me: Can ghosts move the pages of your book?
Sage: No, they're not real.
(Well done my young Pad-wan)
