I was looking at the wall of terrariums filled with lizards, iguanas, and other such reptiles. They all seemed tired and depressed, so I flipped the switch that turned on all of their blacklights, causing most of them to scintillate with fluorescent glows surrounded by a purplish light embrace. But the chameleon on the upper rung was still in darkness; one of his two small blacklights had gone out. Moments later, he scurried over to feel the love of the working lamp.
