Snapping away with my lovely Olympus digital camera on Sunday, I wondered why suddenly my pictures looked like postcards or the type of thing you used to get on jigsaw puzzles. Then I realized it was because the sky is perfectly clear and blue, something that only happens on postcards and jigsaw puzzles. As a child, that land where trees are bottle green, the sky is electric blue and roses the colour of Colgate hang over the door of spotless white thatched cottages seemed as foreign to me as outer space. No wonder: Sunday was one of the only times I’ve ever seen it.
