"He really said all of that?" John asked as he tucked into dinner with Mycroft. It was a different restaurant, but no less posh and formal than the last place they'd eaten at.
"Oh yes. He was really very angry." Mycroft replied, cutting his steak into smaller pieces.
"I'm not sure whether I should be happy or sad about his reaction." John said, sipping his wine, "On one hand, I'm pleased that he cares what I think, but on the other hand I'm offended that he doesn't trust me."
"He does trust you, John." Mycroft pointed out, "He takes you on adventures with him and trusts you to save his life."
"Saving his life and being his blogger is one thing, Mycroft, it would be nice for him to actually share his life with me too. I want to know about him, just like I want to know about you." John replied with a sigh.
"Talk to him, ask him your questions." Mycroft urged, "I don't want him to think that I'm telling you all of his secrets. Ask him and he might tell you a few of them himself."
John laughed a little, "I doubt that will go well. I'll bet you 50p that he storms out of the room." he said.
"You're on." Mycroft laughed, sipping at his own wine, "How about, if you win the bet, you treat me to a Big Mac at McDonald's?"
"You're really determined to have some fast food, aren't you?" John chuckled, "Alright then, if Sherlock storms out, I'll take you to McDonald's."
"Diets are made to be broken." Mycroft replied with a smile.
"What secrets of my past did Mycroft reveal tonight?" Sherlock asked without looking up from his microscope when he heard John come in.
"None, actually. He suggested that I should speak to you about your secrets." John replied, slipping off his coat and hanging it up.
Sherlock looked up and frowned, "What's that supposed to mean?" he asked.
"Mycroft said that he doesn't want to tell me things and betray your trust, so you tell me them instead." John said, making a cup of tea.
"I have nothing to share." Sherlock replied, looking back into his microscope again.
"Sherlock, I have lived with you for a reasonable amount of time now and I know barely anything about you!" John sighed, "Why is it so hard for you to share things with me?"
"Mycroft is there for you to share things with, that's what relationships are for." Sherlock replied, getting to his feet.
"Sherlock, come on, just trust me." John said, putting the teabag into the hot water in his cup, "Let's start with something easy. Where did you go to university?"
"Ask Mycroft, John. I'm sure he's more than happy to share everything with you." Sherlock snapped before he stormed off into his bedroom and shut the door.
John waited a couple of moments before he called to his flatmate, "Do you want some tea?"
When no response came, John got to work making a second cup of tea anyway. He sat down in his armchair, holding his own tea to warm his hands. He ignored the movement behind him as Sherlock emerged from his bedroom, collected his cup of tea and shut himself away again.
