A**m saw some random, possibly homeless guy carrying something relatively lightweight. He couldn’t quite tell, but he would have sworn that it was just a stick. The man was hunched over at the waist and making his walk so laborious that it looked as if he was carrying a suitcase full of bowling balls rather than a stick. “Maybe it’s a stick of some as-yet-undiscovered element,” *d*m thought to himself, “Something with, like, a hundred pounds more mass than it would appear to have.” It was then that **am knew. He understood the guy’s burden. He knew that he had had that same pained look on his face.
