"Wait. You don't know how to dance?" It was a quiet day at Baker Street. The two men were sitting, waiting for someone to show up, though it seemed unlikely. Mary was out for the day, looking for a wedding dress.

John chuckled. "No, I don't." Sherlock sat straight up in his seat.

"Your wedding is in three weeks!"

"How hard could it be? It's just swaying." Sherlock sighed. "You are completely and entirely hopeless." John rolled his eyes. "I think I'll figure it out, Sherlock." "What if I teach you?" "I'll be fine." Sherlock stared at him. "Please?"

John sighed. "Fine. If it will make you feel better." Sherlock jumped up, with the gleam in his eye he only got from a good murder.

"Okay! So, would you prefer foxtrot or waltz?" John looked at him with confusion. "Where did you learn this?" "Well, for a case once I needed to infiltrate-" "So YouTube then?" Sherlock's shoulders slouched. "Yes. Foxtrot or waltz?" "Waltz, I guess?"

"Perfect. So, first you need to learn the steps." He turned to face the wall filled with bullet holes. "Do what I do." John rolled his eyes, but did as he said. "I really don't know why we're doing this." He sighed.

"First things first, feet hip distance apart, arms relaxed at your sides." Sherlock made the changes, and John followed suit. "Now, step forward with your left leg. Bend it slightly, and land on the ball of your foot." "Are you quoting WikiHow directly now?" He joked, but he did what Sherlock said. "As a matter of fact, yes. But anyway, do the same thing with your right. They should be about shoulder width apart now." "Mkay," said John, "Next?"

"Move your left foot in towards your right. They sthould be just barely touching." Sherlock turned back to look at John. "Not quite. Move them a bit further apart. No, not that much. Perfect!" John rolled his eyes for the third time during this dance lesson. But, part of him was enjoying it. "Now we step back with the right foot, keeping the upper body relaxed." Both of the men did this. "Now, do the same with your right. They should be about a foot apart." He sighed wistfully. "And, move them together, which completes the box step," He said, "That will be the general move you'll use when waltzing."

"Okay, I think I've got it," said John. "Okay, show me." That caused the fourth eye roll of the afternoon. "So, feet hips distance apart," John said. He changed his positioning. "Left leg forward, right?" "Correct." "And we do the same with the right," He murmured, "Then move the left touching the right, step the left foot back-" "Right foot." Fifth eye roll. "RIGHT foot back, do the same with the left, then put them together, rinse and repeat."

"Great! Now, you just need to learn how to do it with a partner." John laughed. "Okay, fine," He said, "I'll try it." "Wasn't a question. So, we stand shoulder distance apart." They both moved to do this. "Now, you're the lead. Put your right hand on my left shoulder blade." Despite Sherlock anticipating this, he still tensed up when John touched him. "Now my left hand goes on your shoulder." Said Sherlock, "And you just need to do the box step that I taught you. I'll do the part of the follow." Sherlock got his feet positioned. "A waltz is done with a three count tempo. Step forward on the one, to the side on the two, and together on the three."

They started the dance. "John, you're terrible at this." But they continued. John really was terrible. They kept running into the chairs. But they continued.

Gradually, they moved in closer. And closer. Eventually, they could feel each other's heat. After a few more steps, they found their lips touching. They held for a second, then pulled apart. "I..." Sherlock stuttered, while stepping back. "Um... I need to... I'm going to go for a walk." John seemed just as flustered, so he simply nodded. After Sherlock had left, John fell back onto his chair.

By the time Sherlock got back, Mary had arrived. Nothing more happened between the men. But, every glance between the men held just a bit more weight.
