UFO Sighting of two dancing orange balls

At 3.40am on 4th August 2008 I was lying in my garden to escape the heat inside, which was preventing me from sleeping.  I was looking up at the sky when suddenly two orangey coloured balls appeared in the sky, travelling at some speed and seemingly dancing or playfully sidestepping each other.  They travelled much faster than any aircraft but it was difficult to tell if they were only a few hundred metres above the ground or many miles up in the sky.  They were moving southwards and totally disappeared somewhere above the ocean.  The whole thing lasted only about 10 sec
