The running joke in the industry is that the three P's, pets, pools, and parking, create the vast majority of issues between neighbors and within communities. They are certainly not the only areas of contention, but they are definitely up there on the list.
So what can each of us do to be a better neighbor? The next set of Pearls of Wisdom provide a top 10 list for Being A Good Neighbor.
11. Love thy neighbor
12. Respect thy neighbor
13. Curb thy dog (and scoop) 
14. Don't play the stereo too loud
15. Park in your own space
16. Don't be a six-car family
17. Clean up after yourself
18. Take care of your property
19. Help form a neighborhood watch
20. If there is a problem, talk about it - direct conversation is more effective than sending a letter or banging on a wall
Actually many of these items remind me of Robert Fulgham's popular book, "All I Ever Really Needed To Know I Learned In Kindergarden". Share, play fair, clean up after yourself, and say sorry when you hurt someone are all lessons we learn as children and somehow forget when we become adults.
Here at CAI we frequently use the term "be reasonable". And while there is always the possibility for reasonable people to differ, they can also almost always find a reasonable solution to any problem.
"And it is still true, no matter how old you are, when you go out into the world, it is best to hold hands and stick together." (Robert Fulgham)
