It was a normal day on Baker Street. Sherlock was pacing in front of the window and complaining about not having a case to solve and John was sitting in his chair by the fire typing up their latest case.
"John, I need a case!" Sherlock complained, kicking the table as he passed it.
"We just solved one, literally an hour ago." John replied incredulously, peering at the detective over the top of his laptop. The man could get bored like a child.
"But I'm bored now. It's been one hour too long." Sherlock whined as he flopped onto the sofa and then kicked at the cushions.
John sighed and rubbed his temples "Why don't you go get some milk from the shop? We're running low." He suggested merely to get the man out of his hair for a few minutes.
Sherlock turned to face John and made a face "Milk?"
John nodded "Yes, milk. Y'know the stuff we put in tea."
"I know what milk is John." Sherlock muttered "I just don't think milk warrants my effort to go and get it."
"You really are full of yourself aren't you?"
A glare from Sherlock however he mumbled "Yes, that's who I am." Then stood up and headed into the kitchen.
"Fine well I'll go get the milk then." John gave up on his blog and slammed his laptop shut, also standing up as he grabbed his wallet "I'll be back in a bit." Then he headed out the door.
An hour later and John returned with his hands full of bags, having decided to pick up some other things too whilst he was at Tesco's.
"Sherlock I'm back!" he announced as he entered the flat and dumped the heavy bags down in the kitchen, noticing that the detective wasn't in there.
"Please tell me he hasn't gone out on a case whilst I was gone." He muttered as he abandoned the bags and went to go and find his flatmate.
John checked back in the lounge then knocked on the bathroom door but there was no reply. He sighed again then decided that checking Sherlock's room would be the best idea.
"Sherlock?" he peered his head round the door and was surprised to see the taller man curled up on the bed, fast asleep.
John raised an eyebrow. He hadn't been expecting that.
Sherlock rarely slept but he guessed the case had exhausted him even though he hadn't shown it and he decided to let the guy sleep. He needed it.
John closed the door quietly then went back to the kitchen to put away the groceries.
After the groceries were put away John returned to his chair and continued typing up his blog until it was time for dinner. He made himself a simple spaghetti and left some over if Sherlock wanted some later but he wasn't going to wake him up to eat with the likelihood that he wouldn't eat it anyway and then would only be missing out on the only sleep he'd gotten in a week.
Once he had eaten John read a book and finally decided to head to bed himself. Sherlock hadn't stirred this whole time so he just assumed he was still asleep. He changed into pyjamas and got into bed, falling asleep shortly afterwards with the intention of waking up early the next morning to continue his blog.
