He was a boy who knew only the best way to be sad.
That never sat right in his mind.
Always pressured to try and be happier, the sadbeast learned how to appear happy no matter what might be felt.
His eyes reflected back the joy that other people felt so that the waters of his own soul might be shielded from their prying eyes.
His face was a mask and a mirror. The onlooker wouldn't see a sadbeast, but would see whatever animal they themselves were.
His mirror-mask would show joycrawlers and bubblybees, cheermonkeys and lovebunnies, happypups and pleasureweasels.
Other people found their less fortunate images would be reflected as well,
and so the boy was mistaken for a drearydove and a cryfrog, a hollowflower and a weepinghart.
So perfect was his imitation technique that the sorrowful ones thought they found a kindred heart, while the joyous ones thought they found one of their own brood.
