"Hey, man. How you been?"
"Pretty good, pretty good. I just finished court-ordered rehab, and I've been clean for five weeks!"
"That's great to hear! I hope you keep it up."
"I will. I'm never doing heroin ever again. It completely fucked up my life."
"You can say that again."
"Yeah... so, anyway... do you have an extra room I could crash in for a while?"
"Look, man, I know you're clean right now, but the last time I took a chance and let you into my home, you broke the lock off my bedroom door, stole my wallet, my late grandfather's watch, my wife's post-surgery oxycodone, her purse, and my kid's Christmas presents. Sorry, it's not happening."
"But I've changed! I swear! I'll never touch the stuff ever again!"
"It's only been five weeks, and you're the one who said, and I quote, 'I'm a heroin addict, and I love it.' So no, still not allowed in my house."
"But-"
"No."
Except we're talking about a pedo, so he's automatically infinitely worse than a junkie.
