One day, Pinki was ironing the clothes in her room. After half an hour of ironing, the light went off and Pinki went outside to the lobby of her house to check if there was any problem in the household circuit. At the same time, she listened the voice of her 4 years old daughter from the same room where she was ironing the clothes. Her daughter was about to touch the hot electric iron but at the same moment, Pinki entered in the room and pushed her daughter back from that place.
