A BBC Breakfast survey found that 1 in 10 people haven't spoken to any of their neighbours in the last week. They're doing a series on neighbourhood change, and how a decline in normal neighbourly relations turns into an increasing reliance on the police etc. to resolve disputes.
I don't know if it's a headline in search of a story: to report that 22% think neighbourhoods have become less friendly still means that over 3/4 of us think they're just as friendly (or unfriendly!) as they were, or better.
How many neighbours have you talked to this week? How many have been inside your house, or you in theirs? How many neighbours are your friends, compared with people from work, sport, social events, school gate etc.?
