"Sherlock Holmes!" Mycroft screamed from his bedroom, "I am going to kill you!
"Mycroft! Don't threaten your little brother." His mother yelled at him from the kitchn, "Sherlock, give back whatever you stole from Mikey!" Suddenly, the doorbell rang,
"I'll get it!" Sherlock hollered. When he opened the door, he was greeted by a familiar face, "John! What're you doing here-ahrggh" Sherlock was cut short but Mycroft tackling him to the ground from behind "Get. Off. Me. You. Fat. LUMP!" Sherlock strained from under Mycroft, his feeble attempts at breaking free were doing absolutely nothing whatsoever. "Mycroft, will you please get off him? I'd like him alive when we go back to school tomorrow, Sally'd be devastated if I let you squash him to death.", looking rather annoyed that his payback had been cut short, Mycroft obliged, and skulked off to his room. "Sherlock, I've got something to ask you. Umm. How do I put this"
"Oh course you can come and live with me." Sherlock interjected, then seeing John's baffled face, "From my comfortable position on the ground I coouldn;t help but notice the duffel bag, not to mention the fact when I asked you if you'd like to stay the weekend, you said you were busy, you've been complaining about how your Dad is violent and a drunk, the stretch marks on your left wrist indicate a scuffle, no doubt your argument got physical. I'd love to have you live, we've got three spare bedrooms, although I am using one for experiments, so that makes two, anything to have someone in the house who isn't so incredibly boring."
"I think you've covered everything, let's go ask your Mum." John grabbed his duffel bag and stepped into the Holmes household, and was immediately greeted by Mrs Holmes herself, who inveloped John in a rib crushing hug.
"I 'ear everything' from the kitchen, let's set you up in the spare room."
