Tiffany knew what the problem was immediately. She'd seen it before, atbirthday parties. Her brother was suffering from tragic sweetdeprivation. Yes, he was surrounded by sweets. But the moment he took anysweet at all, said his sugar-addled brain, that meant he was not takingall the rest. And there were so many sweets he'd never be able to eatthem all. It was too much to cope with. The only solution was to burstinto tears.
