Mr. Aggarwal was a very wealthy businessman. One day Mr. Aggarwal was alone sitting at his dining table when a thief entered his house from the back room. He quickly rushed to the room to find the thief looking here and there for costly things he could steal. The thief noticed Mr. Aggarwal and tried to run away from the scene but Mr. Aggarwal caught up to him and grabbed his shirt. He thanked the thief for coming as today was his 40th birthday. He asked the thief to give him company on his birthday. Mr. Aggarwal then gave him good food and drinks. They talked for a long time. At the end of the day, Mr. Aggarwal again thanked the thief for coming and giving him company. As a gesture of thanks, he gave the thief a purse full of silver coins. The thief happily accepted it, said goodbye to Mr. Aggarwal, and went away. Years passed by and Mr. Aggarwal's fortunes changed. His business was ruined. Mr. Aggarwal became poor because of this. On his 50th birthday, he was all alone. He had no food to eat. No drinks to drink. Suddenly, his doorbell rang. He went to the door to answer it. A man emerged looking in his thirties. Mr. Aggarwall quickly recognized the man as the old thief. This time the old thief came to wish him a happy birthday. He came with fruits, sweets and drinks, and a bag full of money. This made Mr. Aggarwal happy.
