I was on a white, cloudy cliff of Dover on a sizzling hot day looking out to the cystal, clear ocean. Suddenly I saw a surfer gliding on the waves. He was just finishing a magnificent surf, but when he did finish ther were about seven great white sharks surrounding the surfer I wondered what I would do ... Should I call all 999 or should I jump of the cliffs and swim to save him? I chose calling 999 but there was no signal...
