"Don't argue with me John, it does nothing to prove your intellect," Sherlock said, condescendingly. John rolled his eyes and bit his tongue, choosing instead to focus on Bailey, propped up against his shoulder as she snoozed with contentment.
"I'm not ARGUING, Sherlock," he protested. "I'm simply pointing out that perhaps Greg and Molly may already have plans for their anniversary and perhaps don't necessarily need help from US. Meaning YOU."
Sherlock heaved a heavy sigh as Bailey stirred in John's arms. "Here," he said, "let me take her for a bit." John didn't protest as Sherlock took the tiny girl from him, handing over Rosie in return.
"And if they DON'T have plans… I mean it would be a miracle if either of them even REMEMBERED the day…" Sherlock retorted, adjusting the baby in his arms.
John raised his eyebrows in disbelief, shaking his head. "Really, Sherlock. REALLY? This is Greg Lestrade we're talking about. He could be bloody CATATONIC and STILL remember his anniversary with Molly. And Molly is even LESS likely to forget her anniversary with Greg. She's a romantic at heart, remembering things like that are just… her THING."
Sherlock huffed a dramatic sigh, looking right at Rosie. The girl cooed as he shook his head sadly and declared, "Rosamund, your daddy can be SUCH a bother!"
