I think the ultimate goal to live with neighbor's  is to live in peace and harmony, and even though that’s not always possible, you can at least do whatever it takes to prevent hostilities and long-lasting hard feelings. Observe and respect your neighbor’s personal space. Try not to borrow anything, but if you must, return the item immediately after using it. If you break the item, pay to fix it or replace it. And last don’t be the neighborhood gossip. That’s just rude and will eventually come back to bite you.
