Oh, such a beautiful and moving photo. Thank you for sharing. And the answer to your question?
No, they are not so different.
I really wanted to share this photo with you all. It was taken at a nature reserve (not sure of the exact location) after the passing of one of the higher ranking females. The female suffered a fatal heart attack, and whilst her body was being carried away, all of the troop stood and watched, in what is being described as a mourning. This photo really touches my heart and I hope it will do the same to you. Are we really so different to them?
