All fungi are edible. It's just that most are edible only once. -- Anon Guest
[AN: I recognise that Terry Pratchett quote!]
"There's food all around us," said their nature guide. Teaching these wayward kids some wilderness survival skills. "Can you point out what's edible?"
Tilly, the quiet one, said, "Everything. The real question is: what's edible more than once?"
Nature Guide Sam winced. Right. Some of these kids were on the spectrum and took things to literal extremes. Or extreme literalism, depending on where you were standing. And since they were also abused, it was a careful exercise to correction and getting these kids on the right path.
