" I hadn’t realized that this whole “water” thing was going to be an issue for me. I mean … half the world is water, right? And we’re all half water to boot. So stepping into the sub should have felt like a sheep falling into a big pile of cotton.
Only it didn’t. It felt like a sheep falling into a pile of nails. Wet nails. On the bottom of the ocean. "
