How to Get Along with Neighbors

I like my neighbors, and as far as I know, they like me too. We all follow a simple and easy protocol based in common courtesy and common sense, which is:

1. We don't play loud music. I never do, party or not, because of personal preference, but my neighbors don't play loud music more than once in a blue moon, and I can accept that very rare occasion, especially since it is always during the day and never at night.
2. We keep our animals out of each others' yards, with the exception of cats, which are welcome to patrol our yard and keep the chipmunks, birds and squirrels in check, and the occasional straying of a family dog, which is understandable, dogs being dogs. The dogs are non-threatening, friendly dogs, which is a key factor.
3. If the mailman screws up and puts the neighbor's mail in my box, I deliver it to my neighbor. I don't know whether my neighbors return the courtesy or not, but I haven't been missing any mail to my recollection.
4. We try to keep the front yard, with its high visibility to the neighbors, in good shape, although we don't mow every week like many uptight people do, because to me it seems like a waste of time, gas and constitutes a moderate level of noise pollution. If my neighbor wants to mow every single week or even twice a week then that is his business, not mine, but I don't plan to copy his behavior.

Of the above list, #1 is by far the most important. Loud music is the most effective way to transform a harmless, neutral, or even friendly neighbor into your worst enemy, even a deadly enemy in one recent case in Texas.

I used to live in an apartment complex, and the fellow that lived above me played extremely loud music on a daily basis, from the time he woke up to the time he went to bed around nine in the morning, which caused me to hate him, because one of the things I value is peace and quiet. It took a while, but eventually I succeeded in getting that SOB evicted from his apartment on an unrelated transgression--his littering of the apartment complex. His trash was blowing over into a nearby homeowner's yard, and the homeowner knew the landlord, so on my prompting she called him up and complained. Problem solved for me. Bad neighbor moved out, and new neighbor moved in. The new neighbor was quieter, although they too played the loud music about once a week. But once a week is better than every day. Eventually I saved up enough money to move the hell out of the apartment, and I bought a foreclosure. In today's economy, I feel sorry for anybody renting who can't take advantage of the low house prices of the many foreclosures on the market.
