Charisma is there or it isn’t.
Tuan Tuan is the youngest panda at Taipei Zoo and as you can see is a charismatic fellow, sitting patiently while his many visitors coo and take his photograph. He even gave me a little eye contact. It feels slightly awkward when you realise something is looking at you. Most animals seem to ignore humans.
I think the first time I really noticed an animal looking at me was at Brighton Dolphinarium. I had gone there to see a show (for my sixth birthday I think) and as I walked past the front, I saw the a dolphin look back at me. When I think back on it, I imagine it was probably a pretty horrid palce to be a dolphin, but I have been fascinated with them ever since.
