Come one Marcio, stop it! You know that you know a lot! Don’t play around with your knowledge.
In my opinion, neighbour has also a meaning of a “fellow”, someone that you know.
Here a little information about the word Neighbour:
Loving one's neighbor as oneself would be much easier, or perhaps much more difficult, if the word neighbor had kept to its etymological meaning. The source of our word, the assumed West Germanic form *nāhgab r, was a compound of the words *nēhwiz, “near,” and *b ram, “dweller, especially a farmer.” A neighbor, then, was a near dweller. Nēahgeb r, the Old English descendant of this West Germanic word, and its descendant in Middle English, neighebor, and our Modern English neighbor have all retained the literal notion, even though one can now have many neighbors whom one does not know, a situation that would have been highly unlikely in earlier times. The extension of this word to mean “fellow” is probably attributable to the Christian concern with the treatment of one's fellow humans, as in the passage in Matthew 19:19 that urges love of one's neighbor.
