This is an absolutely true story.
One of my cousins, who's a bit older than me, went to work in Kenya after graduating from uni in the mid-80s. On a hike through the bush, he came across a young bull elephant standing with one leg raised in the air.
The elephant seemed distressed so John approached it very carefully. He got down on one knee and inspected the elephant's foot, and found a large thorn deeply embedded in it.
As carefully and as gently as he could, he worked the thorn out with his hunting knife, after which the elephant gingerly put down its foot. The elephant turned to face him and with a rather stern look on its face, stared at him. For several tense moments John stood frozen, thinking of nothing else but being trampled. Eventually the elephant trumpeted loudly, turned and walked away.
John never forgot that elephant or the events of that day. Twenty years later he was walking through a zoo with his teenaged son. As they approached the elephant enclosure, one of the creatures turned and walked over to near where John and his son Alex were standing. The large bull elephant stared at John and lifted its front foot off the ground, then put it down. The elephant did that several times then trumpeted loudly, all the while staring at him.
Remembering the encounter back in the 1980s, John couldn't help wondering if this was the same elephant. He summoned up his courage, climbed over the railing and made his way into the enclosure. He walked right up to the elephant and stared back in wonder. Suddenly the elephant trumpeted again.
It wrapped its trunk around one of John's legs and hurled into the enclosure wall, killing him instantly.
So it probably wasn't the same elephant.
