COAST IS CLEAR

No enemy or danger is in sight; there is no one to see you. * /When the teacher had disappeared around the corner, John said, "Come on, the coast is clear."/ * /The men knew when the night watchman would pass. When he had gone, and the coast was clear, they robbed the safe./ * /When Father stopped the car at the stop sign, Mother said, "The coast is clear on this side."/
