I wasn't intending to continue this, which is why the first chapter is so long. But people really wanted to hear what Sherlock said so here you go.
"I wont do it again" Dan said as John left the room, bring his knees up to his chest and resting his chin on them, "I promise"
"You need to be careful" Sherlock nodded sitting down next to him, "These things can take over your life without you even noticing"
"I've seen addicts Dad I live on the street" Dan didn't look at him, Sherlock knew any other time he would of added, 'I'm not an idiot you know'.
"You don't live on the street" Sherlock corrected
"You know what I mean" He muttered, "Point is I know getting involved with that kinda thing is bad, I dunno why I thought it was a good idea but it made sense at the time"
"It often does" Sherlock agreed, "You don't want that life, believe me I know"
"You've seen it too?"
"I've lived it" Sherlock admitted after a few seconds, Dan's eyebrows shot up into his hair.
"So has your mother, but she was not nearly as bad as me" Sherlock continued, not really caring. He'd never kept his past a secret from the kids on purpose, it just, never came up.
"You were a druggie?" Dan gaped, Sherlock nodded.
"Seven percent solution" Sherlock drawled, "It's actually how I met your mother, though she was clean by then, helped me get clean as well. That was almost ten years ago now when your mum wasn't much older than Joe"
"So, you've got a lot of experience with it?" Dan mumbled
"Years, the worst years believe me" Sherlock sighed, "Haven't touched the stuff in a long time, it was something I had hoped to keep you all sheltered from"
Dan snickered.
"Good luck" He chuckled, Sherlock smiled.
"Was mum into cocaine too?" Dan asked, looking curious. Other children might of been nervous about such a question but bashfulness was not common among the Irregulars.
"I don't know" Sherlock admitted, something that didn't happen often, "I never asked and I don't think you should either"
"Right" Dan nodded. Sherlock ruffled his hair and stood.
"We'd better give John his room back don't you think?" Sherlock suggested, Dan hopped up and headed towards the living room when Sherlock stopped him.
"You do realize your grounded for at least three months right?" Sherlock raised an eyebrow.
"Aw man!"
