Overview
Sharing resources with a neighbor or a casual acquaintance could have a very stressful effect on your relationship with that person -- so try to keep your hands on what's yours today, and don't ask to borrow anything (even if it's just an egg or a cup of sugar!). Today, at least, good fences make excellent neighbors. Make sure that your boundaries are well defined, and you'll be able to avoid making assumptions that could come back to haunt you.
