In this heart-breaking picture taken at Diergaarde Blijdorp Zoo in Rotterdam, the Netherlands, a giraffe is kissing a dying zoo keeper his final farewell.

Terminally ill Mario Eijs, 54, had worked in the zoo for 25 years, so his last wish was to return to the zoo and say good-bye to the animals he had cared for. Thanks to the Dutch Ambulance Wish Foundation, which took Mario to the zoo and brought his dream to fruition.
