On Fridays, the children would line up, all glittery pink shoes and Ninja Turtle T-shirts, and hike up a steep driveway from the preschool yard to the temple sanctuary. They walked single file or in pairs, one teacher in the lead and another bringing up the rear, each holding one end of a rope. The kids, 3 and 4 years old, gripped the length of the rope with their little hands stained with watercolor paint and Play-Doh dye. You could hear them singing Shabbat songs as they walked, and later, as they poured into the aisles and climbed onto the chairs in the temple and tried to sit still for a whole 20 minutes. By noon, when parents went to take them home, they were spent and tousled, excited but worn out by the morning's exploits. In their backpacks, they carried small challahs they had baked for that evening's dinner.
