"Aughh that's my foot!" Sherlock yelled at John.

"Not my fault you have bloody huge feet," John retorted. "And you're not supposed to be the leader. I am."

Sherlock sighed. He walked over to the iHome player and stopped the waltz that he was teaching John to dance to. "In order for you not to look like a buffoon on the dance floor on your wedding night," Sherlock made a face at the word 'wedding', "I am teaching you how to dance a waltz. So…" He makes a gesture for John to finish his thought.

"Sooo," John said, head lowered, looking out from under his brow. He just stared at Sherlock as he started to hop from one foot to another, impatience apparent on his face. Finally, Sherlock threw his hands up. "So, I have to be the leader until you learn! Seriously, how do you get anything done with that empty head of yours?"

John rolled his eyes. "Whatever. Can we get done?"

Sherlock went back to the iHome and pressed play, fully expecting the waltz to come back on, but it didn't. 'Carry on my Wayward Son' by Kansas did.

The first lyrics belted out and Sherlock jumped back in surprise. John's head shot up and he stared at the music player. The boys looked at each other and burst out laughing. Sherlock started to sing the song as John played air guitar, getting on his knees and strumming with the song.

Mrs. Hudson peeked in the door and immediately backed out, shaking her head. "Boys will be boys," she said and left them to their 'lesson'.
