How about steal from the guy who stole from me first.
Why would you do that?
He's horrible, I want to take revenge.
I'm sorry that you got stolen from, but you should have reported that to authorities. Stealing back from the person makes you just as bad as that person, not to mention that it's illegal to do so. Did you know the guy and why haven't you reported it yet?
I know the guy and I kept it low because I didn't know what to do.
You still can call cops on the guy. It's better than stealing from them and getting in trouble.
