Thanks. Your post was really helpful.
I could still be a good liar. It's just that I really hate lying. I even studied the facial expressions of lying. Hey, at least the cops before believed my story that I invited him over to just chill.

Yeah this thief is really ghetto and has a crinimal record.
Me and Pedro are just nice kids. I bet I can keep a secret but I hope he can too. He's kinda dumb so he might let shit out, I dunno..

But why would the thief just admit it anyway? I'm thinking they might try to figure out why a person like him was with people like us. If they find out he's a dealer somehow then it's all over.
The detective I met went as far as asking me what I do with Pedro when we chill. There's no way they're not gonna ask him specific questions why he would come over.
