Re: Would your neighbours lend you milk, sugar etc. if you ran out.
As long as me and my neighbours know each other are there for emergencies l never ever bother with them.
When you've had one who engaged in heavy breathing phone calls to you (though more funny than frightening) and had the police knocking on your door to investigate a report you've issued a death threat you decide to mind your own business.
I tend to smile over them now ... but didn't at the time.
