The platinum hoop on a chain around Sherlock's neck catches John's eye as Sherlock throws his head onto John's lap. He runs his fingers fondly through Sherlock's hair before fingering the necklace.
"Sherlock?"
"Hmm?"
"Why don't you ever wear your wedding ring?"
Sherlock makes a disbelieving noise that reverberates through John's lap.
"I'm wearing it now."
"Sherlock," John's voice is playfully chiding, but there's an undertone of hurt hiding there. "You know what I mean. On your finger. In public."
Sherlock disentangles the ring from John's hand, studying it for a moment.
"It's precious to me, John. I don't want to damage it with chemicals, or worse, lose it."
John's fingers work absently through Sherlock's curls. "Mmm, I appreciate that, but what about when you're not at work? You're not embarrassed, are you?"
Sherlock sits up so abruptly, he nearly collides with John's head in the process. His hair's a hilarious mess and his eyes are wide and startled. "Oh god, no. John, you don't think that, do you? I'll make an effort."
The look on Sherlock's face is so earnest that John just smiles, kissing his cheek gently.
The next time they manage to head to dinner, Sherlock makes a point of dressing up. John's heart swells when he catches the ring on Sherlock's finger, glinting in a sun beam.
