People are busy, and anyone born after 1975 probably grew up in the same kind of atmosphere as now, where neighbours no longer said hello in passing, and certainly don't take in each other's washing if the rain comes on, mind each other's children, borrow a cup of sugar if they had run out, or knock on the door and ask you in to theirs for a cuppa.
Some keep their distance, because like me, they have learned the hard way that neighbours who are friendly these days, are on the scrounge. One of mine can't be bothered to learn the language properly after having lived here for 18 years or so, so was in and out of our house every other day, asking could I phone social security for her, her bank, the hospital or whoever else had written her a letter she could not read.
As she has an adult daughter living at home, I started saying no - it took far to long to explain things to her, as I do not speak Arabic, which her daughters do.
