As usual on this type of thread, there are a bunch of people who are utterly incensed that you won't socialise with neighbours or have the world and his husband round your house. Pearl clutching and outraged that people would have the temerity to not want to socialise with neighbours, and nigh on demanding to know why. WTF has it got to do with anyone if someone isn't arsed to socialise? 
And newsflash, just because someone doesn't have neighbours around for tea and crumpets every bloody week, and chooses to not GO to a neighbours for tea and crumpets every bloody week, that doesn't mean that neighbours will be neglected and die, and be there for weeks without anyone knowing FFS. 
I live in the friendliest village in the land, and we all chat in the street, and see each other whilst bike riding or walking, and see each other in the local town on market day etc, and church or the local shop, and there is always someone to help you if you need help, but nobody has anyone around their house. Family and close friends yeah but not neighbours.
One woman I used to know (in a town I used to live) had BBQs and parties for ANY fucking thing. Probably 12 a year! And all she did through the whole time she was there was go around asking everyone if they were OK, if they were happy, if they were enjoying the party., if they were enjoying the food, if they thought she was a good host, if they liked how she and hubster had done the garden, and she even said to her husband 'I'm a good wife ARN-I?! It made me cringe. We went to 3 or 4 of her 'do's,' but then kept making excuses to not go. Especially as half the time, her grotesque chavvy family were there and were morbidly loud.
When we left the area she asked us eleven times for our new address (during the 3 weeks prior to us going.) In the end we gave her a false one. The thought of her and her noisy family turning up in our quiet little village was horrific.
For the record, a new neighbour asking the whole street around shortly after moving in, is a bit odd imo. I wouldn't go. If it was someone who I know and have spoken to quite a number of times, then I may go, but it's unlikely I would go if I didn't know the person inviting me.
