Kalpana Chawla was extremely proud of her birthplace and made every effort to bring it into the lime-light. During space flights she would proudly point it out to her fellow-astronauts. Once, during the second flight she remembered her closest friend, Daisy Chawla, who died in a road accident. In fact, despite her celebrity status, she took pains to track down her former teachers, classmates and friends in Indian and showed a keen desire to stay in touch with them. Her affectionate and humble nature won the hearts of all who came in contact with her.
Although Kalpana had a strong desire to go to Mars, fly over its canyons and die in space, she was equally concerned about the well-being of the earth. She always urged young people to listen to the sounds of nature and take care of our fragile planet. During her space trips, she took many breathtaking photographs of the earth for various terrestrial studies later on the ground. When she was in space, she always felt a sense of connection with everyone on the earth.
It was Kalpana's cherished desire to visit India again. But that was not to be. A few months after her tragic death, Harrison visited India. He went to her school and college, met her family, teachers and friends and scattered her ashes over the Himalayas.

By this time, I felt very small
And now my tears began to fall.
I quietly went and knelt by her bed,
''Wake up, little girl, wake up'', I said.
''Are these the flowers you picked for me ?''
She smiled, ''I found'em, out by the three.
I picked'em because they're pretty like you.
I knew you would like'em, especially the blue.''
I said, ''Daughter, I'm sorry for the way I acted today,
I shouldn't have yelled at you that way.''
Why did the mother go to her daughter's room ?

[You may begin with : My son never saw the skeleton in the cupboard…]
Yes, there was a skeleton in the cupboard, and although I never saw it, I played a small part in the events that followed its discovery. I was fifteen that year, and I was back in my boarding school in Simla after spending the long winter holidays in Dehradun. My mother was still managing the old Green's hotel in Dehra-a hotel that was soon to disppear and become part of Dehra's unrecorded history. It was called Green's not because it purported to the spread of any greenery (its neglected garden was chocked with lantana), but because it had been started by an Englishman, Mr. Green, back in 1920, just after the Great War had ended in Europe. Mr. Green had died at the outset of the Second World War. He had just sold the hotel and was on his way back to England when the ship on which he was travelling was torpedoed by a German submarine. Mr. Green went down with the ship.
The hotel had already been in decline, and the new owner, a Sikh businessman from Ludhiana, had done his best to keep it going. But post-War and post-Independence, Dehra was going through a lean period. My stepfather's motor workshop was also going through a lean period-a crisis, in fact-and my mother was glad to take the job of running the small hotel while he took a job in Delhi. She wrote to me about once a month, giving me news of the hotel, some of its more interesting guests, the pictures that were showing in town.

[You may begin with : A couple of days later he was walking around .....]
A couple of days later , I was walking around the camp, around the barracks , near the barbed - wire fence where the guards could not easily see . I was alone
On the other side of the fence , I spotted someone : a little girl with light , almost luminous curls. She was half hidden behind a birch tree .
I glanced around to make sure no one saw me. I called to her softly in German . "Do you have something to eat ?".
She didn't understand.
I inched closer to the fence and repeated the question in Polish . She stepped forward. I was thin and gaunt, with rags wrapped around my feet, but the girl looked unafraid . In her eyes , I saw life .
She pulled an apple from her woollen jacket and threw it over the fence.
I grabbed the fruit and , as I started to run away , I heard her say faintly , "I"ll see you tomorrow."
I returned to the same spot by fence at the same time every day . She was always there with something for me to eat -a hunk of bread or better yet , an apple. We didn't dare speak or linger. To be caught would mean death for us both.
I didn't know anything about her , just a kind farm girl , except that she understood Polish .
What was her name ? Why was she risking her life for me ? What was in such short supply , and this girl on the other fence gave me some , as nourishing in its way as the apples.

The next year Dell enrolled at the University of Texas. Like most first-ye,u students, he needed to earn spending money. Just about everyone on campus was about personal computers. At the time, anyone who didn't have a PC wanted one, but dealers were selling them at a hefty mark-up . People wanted low-cost machines custom-made to their needs, and these were not readily available . Why should dealers get such a big mark-up for so little added value? Dell wondered. Why not sell from the manufacturer directly lo the end user?
Dell knew that IBM required its dealers to take a monthly quota of PCs, in most cases more than they could sell. He also knew that holding excess inventory was costly. So he bought dealers' surplus stock at cost. Back in his dormitory room, he added features to improve performance . The improved models found eager buyers. Seeing the hungry market, Dell placed local advertisements offering his customized computers at 15 percent of retail price. Soon he was selling to businesses, doctors' offices and law firms. The trunk of his car was his store, his room took on the appearance of a small factory.
During a holiday break, Dell's parents told him they were concerned about his grades. ''.If you want to start a business, do it after you get your degree," his father pleaded.
Dell agreed , but back in college he felt the opportunity of a lifetime was passing him by. "I couldn't bear to miss this chance," he says. After one month he stacted selling computers again-with a vengeance.
