Mysteries

I awoke Christmas morning and looked out the window at the fresh fallen snow. How delightful, I thought, one of the children in our neighborhood received a new bicycle and she has been riding it in the snow.
When I put on my boots, hat, gloves and coat and carried a shovel into the snow, I realized it was a strange kind of bicycle that would leave two parallel tracks.
How strange. Every few feet, there was a tiny deer hoof print. Or is that reindeer?
