Travelling

Four hours at Dubai airport can seem like a lifetime. Once you've seen the palm trees growing around the oasis they've constructed in the atrium, ogled the wall-waterfalls illuminated in coloured lights, taken the free rail link between two identically decorated terminals and experienced that sense of confusion that makes you think you've arrived back where you set off, read so much of your book that your eyes are tired, there really is nothing to do. :o)
