I got the best Christmas gift ever from my kids. Meilee encouraged Shen to attempt to ride his bike without training wheels. (We took the training wheels off earlier this summer and promptly had to re-install them.) He agreed. And what happened over the course of three days was not just a lesson in physics (Shen fell many times), but the realization of many of the “good-human” qualities I have tried to instill in my children: teamwork, supportiveness, persistence, love, joy, and an understanding of the reward of having accomplished something.
