No problems with the neighbors here... all helpful and decent. Everyone pretty much keeps to themselves, but it's also a given that they'd be there immediately if needed.
Mine also. Sure, I've had some neighbors I've liked better than others, but I followed my parents' template to be friendly (but not overly so) with neighbors - and have been fortunate enough to have neighbors who felt the same.
A 1994 earthquake was severe in our area. It hit in January at 4:31 AM, and all power ceased immediately so it was pitch dark. It took a while - probably 10 minutes - to get our bearings, calm and organize the kids, locate shoes, jackets, flashlights, car keys, do bathroom runs (after reseating the toilet), and so forth.
When we got outside, several neighbors had amassed on our lawn, devising a plan to get into our house to rescue us from the harm they feared we'd suffered. Their relief when we came outside was obvious and touching.
During a severe aftershock a few minutes later, DD was about ten feet away from me. A neighbor who I barely knew was standing next to her, and the woman hugged and soothed DD through the shaking.

Turned out she was a marriage & family counselor. Throughout the week or two that our neighborhood was mostly on its own because the damage was so widespread, we helped each other through and shared our resources.
It was an object lesson: when a crisis hits, neighbors are our closest and most important support system.
