The email that included these photos had several more, but I have chosen a few that tell the story. The man fed the deer some apple, and the deer seems curious about the people and the dogs, but not afraid. I did notice that in all the photos, the man kept his hand firmly on the big dog's collar, so perhaps he thought the large dog was not as peaceable as the smaller dog.
The deer "kisses" all of them in turn. It's wonderful to see them together. Too bad we can't all just show our curiosity about others, and manage to get along no matter what our differences.
