Re: Door locks.
Ditto with the use of the back door. It was only once my parents were in their late fifties and turned paranoid ("all them immigrants in town, coming over here and working hard in our fields") that they got to locking the back door half an hour before sunset and the back gate half an hour after sunset. And then started leaving the gate locked during the day ("Betty down the road got burgled, you know" - Yeah, Mum, that was four years ago, when she was in hospital for a fortnight and the place was signalling **EMPTY** to the world 'cos her lad never bothered with the curtains when he watered the plants morning and evening, and Betty told me aaaall about it yet again just last week).
