"Sherlock, are you feeling all right?"
"Fine."
"Hmm. Do you need anything? I'm going to the shops."
"No. You know I'd have written it down or texted you."
"Yeah. Are you sure you're all right. No fever, nothing like that?"
"I said I was fine. Why do you keep asking me that?"
"It's just. Well-"
"Spit it out john."
"There's nothing on the list. You always have something on the list for me to get. Why don't you have anything on the list?"
"Of course I have something on the list John. See there, I asked you to pick me up more Shampoo."
"But that's not normal! I mean it is normal, for normal people, which makes it not normal for you. You never have me pick up normal things. It's always something unusual, something weird. This is—!"
"John maybe you should lay down."
"I'm fine Sherlock!"
"You clearly aren't. Someone who is 'fine' doesn't go on about things that are 'normal' in a way that confuses even me. There is clearly something wrong. Maybe I should call Mrs. Hudson."
"I don't need you to call Mrs. Hudson! I am fine. I am fine and I am going to the shops, and when I get back I will find out what is wrong with you."
"I told you there was nothing wrong with me John. I really do think you need to lie down."
"You just told me that you were confused! Confused Sherlock! You are never confused!"
"Is everything alright boys? I heard the shouting and thought I should come up and check if everything was alright. Oh my, are you two coming down with something? You look a little flushed to me. The flue's been going round you know. Perhaps you'd better have a lie down. I'll make you each a nice cup of tea. But just this once mind you! I'm not your house keeper."
