The flat was quieter than it had been the entire week- what with foreign killers on Monday, a vengeful swordswoman on Tuesday, and a particularly irritable alpaca on Wednesday (don't ask) and John was rather enjoying the peace and quiet.
Sherlock, for once, was occupied with something that wasn't illegal or deadly. Rather, he was on the couch, updating his blog. John was in the kitchen, preparing a tea. Mrs. Hudson was downstairs, baking cookies (or so Sherlock deduced.)
Yes, all was well on Baker Street.
...At least until the tap-tap-tapping of Sherlock at the laptop paused, and he steepled his fingers in thought.
"John," he finally asked, "what is a legume?"
John paused, setting the tea leaves back on the counter.
"Well, I suppose they're some sort of... er, I'm not actually sure."
Sherlock frowned, black eyebrows furrowing.
"I thought you would know."
John sighed.
"You could just look it up, y'know."
There was a momentary silence, then the clicking of a keyboard.
And then-
"A legume is a plant in the family Leguminosae, or the fruit or seed of such a plant. Legumes are grown agriculturally, primarily for their food grain seed, for livestock forage and silage, and as soil-enhancing green manure. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. Well-known legumes include alfalfa, clover, peas, beans, lentils, lupins,mesquite, carob, soybeans, peanuts, tamarind, and the woody climbing vine wisteria."
John opened his mouth to speak, then wisely closed it.
"That's... that's, erm, superb. Listen, why don't you work on your blog?
"Already have."
"I've finished tea. D'you want a cup?"
Sherlock gave a sort of grunt, which John supposed was a yes.
He brought the two cups in to the sitting room, and they both sipped the tea in silence.
The quiet bled on for the next half an hour or so, and John was getting ready to sit up when Sherlock spoke.
"Funny word, isn't it?"
John frowned.
"What, legume?
"Yes. Just say it a couple times. Legyoom. Legume. Le-"
"Yes, it is quite silly." John replied quickly, before Sherlock could spout any more nonsense.
"-Legyoooooooom."
In an effort to make the conversation at least half-sane, John said "Right! Well, this is all very nice, but if you want tea tomorrow I'd best go get the milk."
Sherlock snorted.
"Don't bother. Mrs. Hudson went to the grocery this morning for her cookies, she's bound to have milk."
"Oh- yes." John said, relieved.
"And John?"
"Yes?"
"Do you think she bought legyooooooooms?"
