Famished

"Why am I on the couch? What are you doing?"

"Because you fainted. And wondering when you last ate."

"Five days ago."

"FIVE? Sherlock!"

"You didn't remind me to eat."

"I was in Cardiff. How did you survive before I reminded you of these things?"

"I remembered to eat and drink. Now that I am burdened with a flatmate with nothing better to do than to remind me, I can put my superior intellect to better use."

"But I'm not always here."

"You should be. "

"Besides… I do have better…"

"Really, John?"

"I should've left you on the floor."
