In a Nut Shell

Dandelion Duck was the curious sort, which often led to her being caught up in some adventure or scrape.
Yesterday was no different, and she wanted to tell her Grandquacker all about it. So she called Message Magpie to give him the longest message he’d ever been asked to deliver.
“This isn’t a message” he thought. “This is an essay” as she was giving such a detailed account of her adventure, and hadn’t even got to the point.
Eventually Message Magpie decided to hurry things along. “What is it, in a nutshell?” he asked.
Dandelion Duck stopped mid-sentence, paragraph three, and looked at him blankly.
“A nut” she answered.
