Can you give an example? I mean, that's… Yeah, I can give loads of examples. For example, with elephants we know that the entire community responds if a matriarch dies. There was one particular example in Africa. A particular community of scientists who followed for seven days, a parade of mourners who came to this particular matriarch who had died. Her name was Eleanor. Not only her family, but matriarchs of other families. Some stood vigil over the body, some rocked over the body. Others showed distress. So my definition of animal grief involves some kind of symptom of distress.
