We've got great neighbors on 3 sides as well, but since we live on a semi busy street we don't really call the people across the street our neighbors
To the north we have an unemployed IT guy in his 60's who is our local security guy/squirl shooter. He's a whoot.
To the south we have a nice young (early 30's) family with two small kids - nice to have kids our kid can play with. Before them was a nice widower who could also be counted on to watch over the neighborhood.
The house just south of them is a college house and can, at times, be a tad noisy, but it never lasts too long and I remember being their age.
Behind us in the alley we have an entire block of good neighbors - not one of them would I complain about for anything...cept that one house where they never say "hi" or even way hello...that's wierd.
So, if it weren't for the busy street we live on (yes, we knew that when we bought) we might have the perfect place.
