    It was at least two months before Christmas when nine-year-old Almie Rose told her father and me that she wanted a new bicycle. As Christmas drew nearer, her wish for a bicycle seemed to disappear, or so we thought. We bought Baby Sitter's Club dolls, and a doll house.

    Then, much to our surprise, on December 23rd, she said that she "really wanted a bike more than anything else". It was just too late. With all the details of preparing Christmas dinner and buying last-minute gifts, how could we take the time to select the "right bike" for our little girl?So, here we were — Christmas Eve around 9:00 p. m. , with Almie and her six-year-old brother, Dylan, settled(安置) snug(暖和的) in their beds. Now we could only think of the bicycle and the disappointment of our child.

    "What if I make a little bicycle out of clay(泥) and write a note that she could trade the clay model in for a real bike?" her dad asked.

    "This is an expensive item and she is ‘such a big girl'; it would be much better for her to pick it out. "

So he spent the next four hours working hard with clay to make a tiny bike.

    On Christmas morning, we were excited for Almie to open the little heart-shaped package with the beautiful red and white clay bike and the note. Finally, she opened it and read the note aloud.

    "Does this mean that I trade in this bike that Daddy made me for a real one?"

    Pleased, I said, "Yes." Almie had tears in her eyes when she replied, "I could never trade in this beautiful bicycle that Daddy made me. I'd rather keep this than get a real bike. "

At that moment, we would have moved heaven and earth to buy her every bicycle on the planet!
