I couldn't resist this picture. Taken as usual from the BBC day in pictures site it shows a water buffalo in Bangladesh - and reflected in her eye - what seem to be eager potential buyers at the market she is being sold at.
It is unnerving to see so much beauty - and realise that the eye is not a human eye after all - but that of the often ungainly looking water-buffalo. It is also vaguely troubling to see the eagerness of the onlookers (buyers?) reflected in the beast about to be bought. The final bit is the opaqueness of the eye. Since it has become a mirror - we see the surroundings, but we have little clue about what this animal is feeling. Even in our friends the humble beasts - the eyes are the window of what is within.
