RESCUED
saved by the bell
rescued from a difficult or dangerous situation just in time by something that brings the situation to a sudden end. (From the sounding of a bell marking the end of a round in a boxing match.)James didn't know the answer to the question but he was saved by the bell when the teacher was called away from the room.I couldn't think of anything to say to the woman at the bus stop, but I was saved by the bell when my bus arrived.
