That feeling you get whilst bobbing in a warm sea, somewhere far from the north Atlantic chill of the UK. And then a cloud encroaches on the scene. It muscles in front of the sun. At the moment you feel disappointment and restive, that you might go and dry off, the rain starts to fall. And it is a revelation. The gentle sting on your skin of warm rain while you are still semi-submerged, you feel in your element.
