"Where else in the world...?"

could you leave a bicycle in the morning, catch the bus and then come back at night and find it still there?"
A fellow knitter posted a picture of a bicycle leaning against a dry stone wall on the island she lives on in the Shetland archipelago - and asked that question.
I responded saying I once lived on an island where you could have done the same thing. At least, you could have left the bicycle and nobody would have taken it. There would not have been a bus unless you happened to be on a route that one of the school buses took during the school week. 
And yes, people did that sort of thing. They left their houses unlocked and their cars with the keys in them. 
Trouble, if trouble came at all, was generally from the "mainlanders". 
I said this to the Senior Cat yesterday. He frowned and said, "There was that accident.....no, they were from here too, weren't they?"
Yes, they were.
I will probably never forget that night. There was a very bad accident on a slight rise near the school and the school house. Some teenage boys from the city had, somehow, managed to get on to the island. They had stolen a car - with disastrous consequences. The injured had to be flown to the city hospital. 
There was no air ambulance in those days. The helicopters that are used were not in existence. The injured were flown out in a "crop duster", a tiny plane used for spraying crops. The pilot who did it made multiple trips in one night - alone with his patients. 
I don't remember what happened to the injured -  if I ever knew. I do remember the pilot working through the night and into the next day. His lights shone directly into the bedroom I shared with my sisters as he used the unsealed road outside our home as a runway. Even at the time I realised that what he was doing was very, very dangerous. 
After that people on the island were told to take their car keys with them. They did for a while but, as one farmer pointed out, "That sort don't need keys to start anything."
I don't know what they do about keys now. The island has changed character. It is now a tourist destination. I suspect people do lock their houses and their cars.
We lived in other places where people did not lock their doors too. The Senior Cat was required to lock the school but, in one place, the only other place that was locked was the police station. On the outlying farms some of the houses didn't even have keys to the doors. There might have been keys to begin with but nobody knew where they were because they had not been used for years, if they had been used at all.
I explained this to Ms W yesterday. She was amazed. As a city child she is thoroughly familiar with keys and the necessity of locking things.
She thought about it for a bit and then, as she was going out the door, she said,
    "I suppose it is different when you all know each other."
Yes, it is.
