Sorry for going off on a tangent, but aren't elephants the most fascinating creatures? I wish I had one, I'd train it like a dog. They are really such social types. Like Italian mothers. I saw a clip of some baby elephant that fell into a ditch in India. The Indians had a backhoe and we're trying to drag it out, while elephants across the river were watching the effort. Finally, they extracted this baby elephant and it scrambled across the river and they all walked off, then the adults came back over the ridge and they all raised their trunks in unison and bleated a call across the river, which could only be a call of thanks for rescuing their brethren. Then they walked off again.
