I like being polite and friendly to my neighbours but I don't want to actually be friends with them...I think a lot of people feel similar.
Yeah this. And I am sick of the nasty mocking, and piss-taking from some posters on this thread, who are pouring scorn over people who are different to them.
It's people like them who cause people to be anti-social, because they are so fucking pushy, nosey, and irritating, and they want everyone to 'come round to their house,' and expect a invite back. In addition, they have this virtual 'love me love me LOVE me' banner hovering over them. It's a bit desperate and needy tbh.
As I said, no wonder people get anti-social with such pushy fuckers around, virtually demanding that they are sociable and friendly with them, and sneering at anyone who doesn't fit their idea of how a 'good neighbour' should behave. And calling them 'weird,' and 'rude,' and 'sociopaths' is just nasty! Who the hell do some people think they are? It's a wonder they have any friends at all! They probably don't and this is why they are so desperate to make new friends! 
Most people have already stated that they say hello when they see neighbours, and will have a chat on the driveway, and will help in an emergency, but they don't wish to take the relationship any further. Anyone who doesn't think this is acceptable, can bore off.
Some of the pushy fuckers on here sound like proper 'nightmare neighbours.'
If people don't wish to socialise and be your 'friend' then deal with it, stop being so pushy, stop taking the piss (because people have the AUDACITY to not want to socialise with you,) and grow up. Not everyone is going to want to be your friend, and saying 'come round for a coffee' to someone as soon as they move in, comes across as desperate and needy.
In my experience, the ones in a neighbourhood who keep asking people round and trying to socialise, often have nothing else to do. Maybe get some hobbies and interests instead of pestering people when they have just moved in, to 'go have a coffee' with you!
