Something is just so right with these two. Love it.
Friends
"Sherlock?" called John when he got back to the flat. Mrs. Hudson's head poked out of her kitchen.
"Hello, John dear. Sherlock's gone to bed early. Came in dripping wet. Odd, I saw him rushing out with an umbrella earlier…"
John looked down at the dripping umbrella in his hand. "…Dammit."
Sherlock was sitting on his bed in his emerald pajama bottoms, a towel around his neck, when John came in.
"You can't go to bed yet. You have midterms tomorrow," John said. Sherlock peered over his shoulder at him.
"You'd help me study?"
"What are friends for?"
Sherlock smiled.
Prompt was #37: emerald (I bet Sherlock looks lovely in those rich greens)
