Someone who doesn’t scream at and abuse their significant others and minds their own business. That definitely sounds like the bare minimum (and is LOL), but we have a crazy neighbor and at this point, we just appreciate the neighbors who are nothing like him. We also don’t have kids or anything currently, and I hear my coworkers talk about how they have nice neighbors who will help them with their kids and/or bus stop things which I find to be very nice! Basically neighbors who are helpful when needed, and mind their business all the rest of the time!
