Reddit reviews The Horse: The Epic History of Our Noble Companion

For all of those people that say that horses are stupid, you should read this book.

She starts out the book by telling an anecdote about her horse whisperer. She forgot to water the horse once, so it opened the coral door (apparently it always knew how to do that, but kept that a secret) went out of the barn, turned on the water spigot using it's mouth and drank. Then went back to the barn and closed the door to hide what it had done. However, it left the water spigot on, so she eventually figured out what it had done (also by spying on the horse). Anyway, like people, horses are very diverse.
