Talk to me about neighbors who don't act all that neighborly. Got any stories about great neighbors? Tell me those, too.
One way to be a good neighbor: You know those young parents without a lot of money who never get out? Offer to babysit their kids for an evening so they can. Of course, this is easier and a lot less saintly if they're also good parents. (I just made this offer to my neighbors, who are.)
