When you buy a house, you should not only be allowed to see information about the house, but you should allowed to interview the neighbours and see what kind of people live around you. You can find a wide range of neighbours, good, bad, and worse.
I can honestly say I am pretty lucky with the neigbours we have. The couple next door is really nice. The guy has once again ( he did it last year ) offered to trim part of the hedge ( the part that I share with him ). I would trim that side without hesitation, but my issue is that its 12 feet tall and I don't have enough ladders to build my own scaffold like he does. Last night, while we were cleaning out the garage, he happened to be in his driveway, and asked us if it was alright if he came to trim the hedge on the week-end. I'm like, its my hedge, your offering to come and trim it for me, of course its alright, I'll make sure everything is ok for it.
Then you get the neighbour across the street. They, aren't really bad neighbours, but they are a little weird. First their dog is CONSTANTLY barking, I would love nothing more than to introduce him to my dog, and that would be the end of it. The last time my dog saw their dog, he was in my yard, and Mason tried to eat him. Mason was yanking at his chain trying to get at the dog ( we tie him up with chain strong enough to tow a car, since he has broken every "dog" chain we ever used on him). Next, they leave their dog loose running around the street, and when you bring it back to them, they are like "ok, sure", and don't really give a care.
All this to say, that I have pretty good neighbours, but I have heard some horrors stories told to me by friends ( that includes you Dom ) that make me think, that before buying a house, you should get to meet these people, to find out whether you are going to get along, or show up on the 6 o'clock news, for multiple homicide.
