L stood at their bedroom window. He was staring out of it with such an intent expression that Light—lounging on the bed—could only think that he must be trying to see something hidden somewhere within the darkness of the night sky. The curtain was less than halfway pulled back, and Light couldn't see anything out of it from where he was lying save for a small sliver of blackness. L had been standing there for a while.
Finally, Light's curiosity got the best of him. "Ryuzaki," he said, not bothering to open his eyes, "what are you looking at?"
From the lack of noise coming from L's direction, Light could tell that the man hadn't bothered to turn around before replying. "Oh, it's nothing, Light-kun. I am simply observing that it is raining cats and dogs."
Wait, what? Light knew for a fact that he couldn't have heard that right.
"Would you please say that again?" he requested. "I didn't understand what you said."
"I was just saying that it is raining cats and dogs."
Confused as hell, Light sat up, slowly. "How does that even happen?" he asked, utterly disbelieving.
L looked at him as though he should know better. "Light-kun, for someone of your intelligence, that is quite an elementary question."
Light did not appreciate being insulted in such a way. "I've never seen it rain cats and dogs."
Suddenly, something seemed to click in L's mind, and he said, "Oh, of course. I apologize, Light-kun. I didn't mean that in a literal sense—I merely meant to say that it is raining very hard out."
"But...how does that have anything to do with cats and dogs?"
L put a finger in his mouth. "It is an English idiom, Light-kun," he said, as way of explanation. "It is only natural for it to not make sense."
Light considered this logic. "Well..." he said, slowly, "I guess that makes sense. But, in the future, Ryuzaki, I would appreciate it if you let me know when you are going to be using such an expression beforehand."
There was a trace of a mischievous smile on L's lips. "Oh, certainly. So long as I don't have a frog in my throat."
Light shot him a glare and chucked a pillow at the man's head.
I'm terribly unmotivated lately, and this crappy story was the best I could cough up at the moment. My writing quality is currently in a terrible state, I know. Thanks for reading, though.
Credit goes to Stormy for suggesting that I write a fic involving a misunderstanding of idioms, which is why I ended up writing this. Review?
