"Come now, Sherlock," Johh said as he set his cup back on its saucer. "Say it."
A disgruntled sigh came from the figure lounging on the sofa.
"I will not."
"You can't say it." John's lips twitched at the grumbling that greeted that statement. "Admit it."
"I shall do no such thing."
"Then say it."
"You bloody well know what."
"I need to get some air," Sherlock announced as he shot to his feet. He swished the folds of his robe about him like a cape and swung around to stare out the window. "We're going out tonight."
"Actually, I have plans."
"What?" Sherlock glanced at him. "Did you say you have... plans?" At John's nod his brow furrowed. "What sort of plans?"
"I am taking Mary to dinner." He sat back in his chair. "And I am still waiting."
"For you to say it." John picked up his cup and took a small sip. "So come on now. Say it."
"I shall do no such thing." Sherlock made his way into his bedroom. "Really, John, you should know me so much better."
"I know you better than you think, Sherlock." Watson reached for the newspaper. "That's why I know you can't say penguin. You are just being an arsehole about admitting it."
"Brilliant deduction, John. Absolutely brilliant."
