Imagine you've just come out of the supermarket, and you're sitting in your car, about to drive away. You reversed into your space, while the car on your right has fronted in. A movement catches your eye, and you look sideways and realise that there's an elderly couple in the car, and they're about to reverse out. You exchange a friendly smile with the lady driver, in an "after you" kind of a way, and she gently moves off, unfortunately applying a scintilla too much right lock, and the car beyond her, a smart little saloon, stirs slightly in it's sleep as plastic scrapes on plastic, and an exchange of paint takes place. There's a damaged patch the size of your hand on the parked car, and the lady is aware she's done it -- her world is suddenly a darker place, worried words are exchanged with her partner, and in some considerable consternation, she drives slowly away. You saw everything, you could have stopped her escaping the scene of the crime, or taken her registration and offered to be a witness for the aggrieved owner -- but something prevented you. You hope it was compassion, but suspect cowardice. The imagined sight of an angry owner berating an old lady looms large in your mind as you drive away, realising that in order to avoid hypocricy, you will now have to forgive those who trespass against your own paintwork. So if you were to find yourself in this invidious situation, what would be your response - and why. Identities have been masked, to protect the guilty. Sunbeem.
