Ice skating, mountain climbing, wrestling, dancing, kayaking, gymnastics, rollerblading, skiing, rock climbing, playing soccer, volleyball, basketball and tennis are among the activities Nicolai has mastered. Today he added riding a bike to the list. He will probably graduate directly to driving a car but I am glad he had the courage to conquer the one skill that remained on the list of challenges he has not overcome. It took him all of about ten minutes to get the hang of it. In order to become fully proficient he will need either a clip in shoe or a toe clip.
