There was a rich couple who was throwing a big New Year party at their house. So they went shopping at the market where everything was of high cost and fixed price. They wanted to maintain their level of standard so didn't mind paying for it. After purchasing all they needed, they called a porter to carry everything and drop it at their home. The porter who came was old aged, not very healthy looking, his clothes were torn, looked as if he wasn't even able to meet his daily needs.

They asked the porter about the charges for delivering their goods at their address. The old porter quoted just Rs. 200, well below the market rate for delivering goods at the couple's home in his cart. Yet, the couple argued and bargained with the porter and finally settled for Rs. 150. The porter was struggling to make even one meal, so he needed anything he could earn.

The couple was very happy thinking how well they bargained with the poor porter and paid him Rs. 150 in advance and left after giving the porter their address for delivery. They reached their home, and one hour passed, two hours passed, but the porter still hadn't delivered their stuff.

The wife started to get angry at her husband, "I always tell you not to trust such a person, but still you never listen to me. Such a person who is not even able to earn to feed himself for one time in a day, you handed him everything we purchased for our big party. I am sure instead of delivering it to our home; he must have disappeared with everything. We must immediately go back to the market to inquire and then to the police station to file a complaint against him".

They both left towards the market. On their way near the market, they saw another porter. They stopped him to inquire about the old porter and noticed that he was carrying their stuff in his cart! The angry wife asked him, "Where is that old thief? It seems you poor thieves are stealing our stuff and going to sell it".

The porter replied. "Madam, please calm down. That poor old man was sick since last month. He wasn't able to earn enough to even have a single meal in a day. He was on the way to deliver your stuff, but being hungry and sick, he couldn't gather the strength to go any further in this heat of the summer. He fell down and while handing me Rs. 150, his last words were 'I had taken an advance for this delivery, you take this and please deliver to this address'."

"Madam, he was hungry, he was poor, but he was an honest man. I was just on the way to complete the old man's last delivery at your home", the porter said. Upon hearing this, the husband had tears in his eyes, but the wife felt so ashamed, she had no courage to look up in her husband's eyes.

Reporters tended to be suckers for every quack, half-quack, over-eager scientist, or naive country doctor who thought he had a serum to cure tuberculosis, a herbal remedy for cancer, or a new surgical procedure to rejuvenate the aged. When the newspapers were not wasting space on: undeserving medical stories, they were overplaying legitimate news, getting their facts wrong, and generally making a nuisance of them interfering in the lives and practices of busy professionals. Doctor's deep suspicion of what they read in the newspapers and even in the less-carefully edited medical journals help to explain some of the early skepticism about insulin in countries like Britain: “Oh, the Americans are always curing everything, this week its diabetes." Even in Canada and the United States, it was some months before there was enough confirmation of the unlikely news from Toronto to convince wire services and the more skeptical doctors and editors that insulin was, indeed, the real thing.

b)      Write a letter to your friend on his Birthday expressing good wishes.

c)      You are the Sports Secretary of your College. Draft a notice in not more than 50 words for your college notice board asking the students to give their names for participation in various events to be held on the Annual Sports Day of your college.
