Isn't it though? It can happen when we pass the natural boundary between us and wild things.
@Freya @Sanguine The article said the giraffe headbutted him, throwing him 16 feet in the air. When giraffes fight for dominance, they use their heads literally, and their odd horns to thrash each other. It is likely the hit was worse than getting kicked by a thoroughbred. He may have suffered the head injury from the hit, or from impacting another object. Either way, it pays to remember that such critters are incredibly powerful and basically unpredictable. If the giraffe saw anything it perceived as a threat, he became the target.
On a softer, gentler note, I saw the bunny who lives in my lilac thicket this morning, sitting upright and alert when I came up on him/her. I just stopped and it stretched out on the ground, on its belly, obviously not threatened at all. You never know how wild animals will react, and sometimes, not even the domesticated ones.
