How did Mary and Joseph feel?

Ever wonder how Mary and Joseph felt, setting out for Bethlehem?  Alone. One hundred miles. It took them five days. It wasn’t like they could drive catch a plane or a bus. They walked or Mary rode a donkey. They were nineteen and fifteen years old!! They had to be very mature for their ages. How would you have felt? How do you think they felt? http://youtu.be/kLMzK-38uqc
