I guess I wasn't so aware of crime then, although I did once find a thief in my garden. He told me straight away he wasn't a burglar, he was a car thief, and he'd 'just crashed a nicked car' and left his friend in the wreckage. Which explained the sirens. I gave him a cup of tea and he got a taxi home. He said he'd 'sort me out' for helping him but he never did. Probably for the best.
