The neighbours that live close to me (one house): I know them well enough to know that i don't want to know them, or have anything at all to do with them. (I have had some "trouble" with them (police/..), and they "rub me up wrong way")
Living in country, all the other neighbours are "miles" away, and so i have barely talked to them, if at all (which if they anything at all like my close neighbour, is probably a very good thing!)
I don't really trust people nowadays. Generally I don't "like" people. And for some reason i seem to "trust" neigbours (or people on my road) even less. Maybe they don't trust me either, and our mutual distrust/dislike "bounces off" each other?
