I never realized
It may sound very strange to say, but growing up I never realized that this story had anything to do with Christmas.
I am not a Christian, and as a small child I was not very familiar with the Nativity story, so I did not know who it was who bought Small One at the end. I always just thought it was a story about a boy who finally managed to find a good home for his donkey. I had it on VHS and could watch it whenever I wanted, so I never even noticed that it was only shown around Christmas time.
When I was a bit older I heard it referred to as a Christmas story, and I became better acquainted with the Nativity story so I was able to make the connection.
I am an adult now, and I still have my old VHS and I'll pop it in from time to time. It is such a truly lovely and heartwarming story. I am fully able now to appreciate the spiritual significance, and I can still enjoy the story of simply finding a good person to take care of Small One.
