Relativity puzzles me. No, not Einstein's relativity — just how things are related on their own. Here's a brief example:

To a chihuahua or other small dog, a jump on the couch is as strenuous as a grown man trying to jump on the ceiling of a one-story house.

So, would that imply that the small bug I just flicked off my desk into a wall was similar to me being thrown off a 5-foot building? There was a very pleasing resounding thunk, but as of now, my morality has kicked in and is damning me to some random circle of hell to atone.

Screw that, I'm going to a party :)
