If you've ever worn transparent plastic shoes, you know how weird and sweaty they can be. Imagine if they were all that and liable to break into dangerous shards, and you can see that a glass slipper is not the best choice in footwear. The moral of the story is: don't look too closely into the details of your favorite fairy tale. That's the way I felt when I read the ancient Chinese version of Cinderella and realized it was, at its core, a tale of a foot fetish from the land of bound feet. This is the latest comic from Zach Weinersmith at Saturday Morning Breakfast Cereal.
