"On one occasion, a group of about fifteen schoolboys were teasing Queenie by offering her nuts and fruit in turn and then withdrawing the food just as she reached for it. This game continued for a while until the elephant retreated to the pool behind her house. She returned some minutes later and, imitating their behaviour, held out her trunk to each boy in turn, withdrawing it before they would touch it. The boys were delighted with this variation of the game until, as if carrying out a pre-planned attack, she soaked them all thoroughly with a well-aimed spray of dirty water from her pool."
