The thing about secrets is that they are usually best kept by just one person. That was the special thing about secrets. Some people seemed to think that the best way to keep a secret was to tell as many people as possible; what could possibly go wrong for a secret when there were so many people defending it?
Terry PratchettTiffany knew what the problem was immediately. She'd seen it before, at birthday parties. Her brother was suffering from tragic sweet deprivation. Yes, he was surrounded by sweets. But the moment he took any sweet at all, said his sugar-addled brain, that meant he was not taking all the rest. And there were so many sweets he'd never be able to eat them all. It was too much to cope with. The only solution was to burst into tears.
