Neighbors can also be rather nice and even useful. They may sign for and hold your
packages for you while you're away, and even return them to you intact. They may help you carry
stuff, see that you're hanging a picture straight,
cook you
dinner, throw good
parties, and yes,
lend you things. It's best that you return such things promptly.
They can also get really toasted with their friends and maybe pound on their floor (your ceiling) during a game on TV, or hawk up mucuous all the time, or hang themselves. You never know. These have all happened.
Neighbors (things), in a networking context, are routers sharing a common data link. Routers in a distance vector network route by rumor, i.e., from neighbor updates; in link state networks, a router sends link state advertisements (LSAs) to a neighbor and those LSAs are in turn flooded to that router's neighbors.
