Hey you! You stole my money!
Nah
Oh yeah? How dare you deny it! You're a filthy thief and I want my money back!
You're pathetic, denying it like that! I'm calling the police right now unless you hand over what's mine immediately!
Fine, then have it your way! You can rot in jail for all I care, you worthless piece of trash! Just know that I'm calling the cops right now and they'll throw the book at you for being such a lowlife thief.
Well if you're not gonna give me my money back, I'll just have to make sure you regret ever trying to steal from me! You watch out, cause Pipi don't play nice when people cross her!
(Your turn to continue the roleplay with a new reply for Pipi.)
Well then, I suppose that leaves me no choice but to find my own way to make you understand the consequences of your actions! Just remember, stealing from Pipi is never a smart idea...
