"John, what is that?"
"It's facial hair, Sherlock." John did not look up from his newspaper.
"Why."
Sherlock stared.
"It's for charity."
Sherlock stared.
Sherlock reached out and pushed a finger down John's upper lip.
"It's soft."
"Yes."
Sherlock scowled.
"I don't like it."
"So?"
Sherlock scowled.
"So I'll shave you in the night."
John looked up from his newspaper.
"Okay. On December 1st."
Sherlock blinked.
"Okay."
John returned to his newspaper.
Sherlock huffed.
