I have an old lady on one side whose a wee star and 2 guys on the other side who are absolute legends, proper neighbours, always thoughtful, generous and really good craic to boot, they also throw proper "grown up" dinner parties and make incredible food. I'm lucky I live in a really leafy/forestry type area so between us all we have big hedges and trees acting as boundary lines so you can be in your drive or out back and it's totally private so no obligation to chat if you didn't want to.
I love the fact that the wife and I can come back from town on a sat nite, walk past their house and if there is a light is on we'll call in for a few night caps that usually ends with us leaving in the early hours.
I would add it's great to know your neighbours well, makes it handy to borrow things, checking on each others houses when the others away, we each have keys and know alarm codes for the others house, there are many many benefits to being close with your neighbours
