Tina DeClue is standing behind a school bus at Shepard Boulevard Elementary School on a recent Friday morning when she hears a little voice call to her.
"Stop, stop," a brown-haired girl in a bright pink shirt says. "I need to tell you something."
DeClue turns toward the approaching girl. "What is it?" she asks.
"You always need to be 10 to 11 feet behind the bus," the girl says earnestly.
