crazy neighbors

Long story and I'm not getting into it. My Ma has  crazy ass neighbors that like to start shit. It's a apartment. They fucking keyed my car today because I parked in "their" spot when it's first come first serve and they like to fuck with us by opening the dryer when we're doing are laundry. They stole shit. How can we fuck with them??????????? Good ideas these fuckers are gonna pay. They have done so much shit and now they keyed my car so now I'm gonna fucking do shot back they past the fucking line
