I told you to stop feeding him cheese, captain.
As a person with trashy neighbours who think they own the street, study how they talk to each other when they want something done then talk to them like that.
I tried being civil with my neighbours, but nothing, then one day I had a shitty day and had enough, walked to the edge of my drive, looked directly at their house and screamed " GET YOUR FUCKING SHIT OFF MY SIDE OF THE STREET OR ILL MOVE IT INTO THE FUCKING RIVER!" walked back inside and about 30 minutes later everything was moved, they behave most the time now, but whenever they try shit again I just do the same thing.
If they're also really loud and you can hear general conversations, make sure to repeat something they know they've said, let's them know you know more about them then they do about you.
Main character seeing old friend: Well if it isn't my old friend Daniel, we used to roam these streets as kids, I used to have dinner at your house every day, you were like my brother, I would have done anything for you, I haven't seen you since our other old friend Jake died mysteriously, remember when we used to play videogames all night and made that life long pact that if "HE" returns we will do what it takes to send him back to the world where he emerged from when we were kids and lived right next door to each other, our mothers were best friends until the incident but they never stopped us from being life long best friends forever, we used to play in the streets all night, me you Daniel and Chris, the rat Pac they called us, best friends for life.
