I saw a family of five out together. The five year old led the pack, on a bike free of training wheels. The father ran slowly beside his toddler aged tow-headed son, who was running as fast as his legs could move, with such joy and enthusiasm. The mother, with her wrist tethered to a jogging stroller that held the baby, brought up the rear. You could see from her expression how much she enjoyed her children, and how proud she was of the family she had helped create. It was really a delight to experience them, even for a moment.
