Simon is a curious donkey, he is very protective of the sheep, he tried to stomp and bite Red for months after Red came, he didn’t want him anywhere around him, but the two have worked it out and now I think Simon wants to learn how to herd sheep, he stands right next to Red, lowers his head and gives the sheep the eye, the way Red does.

This is in the category of animals doing things we will never quite understand, but I think Simon thinks he can herd sheep and is trying to learn. Red seems quite comfortable working with him.
