How to behave like a good neighbour?

I like neighbours who will speak when we see each other. They know that, if they need any help, they can call on me and that it works both ways but I do not expect them to watch by comings and goings or ask intrusive questions. I usually say good morning/afternoon, ask how they are and maybe how their family is doing. If they just say 'fine' that's it. If they want me to know more they'll tell me and the same goes for what i might tell them. I think good neighbours can tell when you have the time/inclination to chat and when you just dont want to.
