It was late in the night. It was a dark and moon less night Shreya and Sudha were very worried. They were alone at home. They had an exam the next day and so they were preparing for the same. Their parents were not at home. They had gone for a movie. It was a usual affair, for them, as they never went with them for outing. They liked to sit at home and study. Suddenly, they heard the doorbell. They were sure that their parents would not come so early. They looked through the window and saw a man ringing the bell. He was a stranger to them. They were scared. They decided not to open the door. They called up their friend who was also their next-door neighbour. He was quite helpful. He immediately came and found that he was a distant relative of their father. He had come to meet him after a long time. All went well after that.
