"Yes, speak quickly." Sherlock glanced up.
"Have you been scaring away Mrs. Hudson's lodgers?"
"Of course not, don't be stupid."
"She said that you keep popping in with your experiments while she's trying to show off 221c and no one will stay five minutes.
There was no response from the armchair.
"Sherlock, you didn't!"
He shrugged. "I didn't want anyone disturbing my work."
"Go apologize. Now."
"John, I'm not five!"
"If you're going to act like one, there's nothing else to do. Get going."
Sherlock groaned, pulled himself up, and stomped out of the room.
