I've mentioned having pockets before, and I've been thinking about them again. Fairly immediately, there's a tension in terms of space, where larger pocket space logically means they bulge out a bit. Then I remembered I already do data compression stuff to allow people larger than my below-average height to fit, so why wouldn't that extend to mildly hammerspace pockets? And once that's established, it follows that if someone else were to stick say a hand in one of my pockets... well, they'd be pulling their paw back out >:3
