Depends on the neighbour.
Although we've owned our house for nearly ten years - much of the neighbourhood has been rather transitional...people moving in and out with 2-3 years. So we've not had any real long-term neighbours to get acquainted with.
The house next to us has been bought 'n sold four times since we've lived here - and with the exception of one owner, most people were disruptive assholes (loud parties all night, domestic fights, etc.).
Another neighbour on the other side we compared to Michael Keaton's character in "Pacific Heights".
