"What was your prom like, Sherlock?" John said, resting the paper down on the sofa next to him. Sherlock looked up, his eyebrows raised.
"Are you trying to make a joke?" he frowned.
"No. I was just curious." He shrugged.
"The fact that you even entertained the idea of me at a prom is hilarious enough." Sherlock said. There was a silence before Sherlock sighed pointedly. "Is this one of those things where you want me to ask the question that you asked me?"
"Sort of."
"Fine." Sherlock hissed. "How was your prom, John?" His tone dripping with sarcasm.
"It was lovely." John responded. "I went with Danielle Potts, long-time girlfriend. She broke up to me once I told her about the army."
"Fascinating." Sherlock said insincerely. John smiled, picking up the paper and unfolding it in front of him.
"You look dashing in a tux, by the way. Blue is your color." John said, nonchalantly. Sherlock's eyes widened and a pink tinge appeared on his cheeks.
"Mycroft." Sherlock breathed angrily.
"Yes." John lowered the paper, his eyes glinting playfully. "The girl?"
"Cousin." He grumbled. "She had a terrible time."
"I'm not surprised." John said, raising the paper again.
