" I know why there is no glass, in front of the watercolour picture of blue irises, and why the window only opens partly and why the glass in it is shatterproof. It isn’t running away they’re afraid of. We wouldn’t get far. It’s those other escapes, the ones you can open in yourself, given a cutting edge. "

― Margaret Atwood , The Handmaid's Tale (The Handmaid's Tale, #1)
