A LONG WALK HOME
By Jason Bocarro
I grew up in the south of Spain in a little community called Estepona. I was 16 when one morning my father told me I could drive him into a remote village called Mijas, about 18 miles away, on the condition that I take the car in to be serviced at a nearby garage, Having just learned to drive and hardly ever having the opportunity to use the car, I readily accepted. I drove Dad into Mijas and promised to pick him up at 4 p.m., then drove to a nearby garage and dropped off the car. Because I had a few hours to spare, I decided to catch a couple of movies at a theatre near the garage. However, I became so immersed in the films that I completely lost track of time. When the last movie had finished, I looked down at my watch. It was six o’clock. I was two hours late.
I knew Dad would be angry if he found out I’d been watching movies. He’d never let me drive again. I decided to tell him that the car needed some repairs and that they had taken longer that had been expected. I drove up to the place where we had planned to meet and saw Dad waiting patiently on the corner. I apologized for being late and told him that I’d come as quickly as I could, but the car had needed some major repairs. I’ll never forget the look he gave me.
“I’m disappointed that you feel you have to lie to me, Jackson.”
“What do you mean? I’m telling the truth.”
Dad looked at me again. “When you did not show up, I called the garage to ask if there were any problems, and they told me that you had not yet picked up the car. So you see, I know there were no problems with the car.” A rush of guilt ran through me as I feebly confessed to my trip to the movie theater and the real reason for my tardiness. Dad listened intently as a sadness passed through him.
“I am angry, not with you but with myself. You see, I realize that I have failed as a father if after all these years you feel that you have to lie to me. I have failed because I have brought up a son who cannot even tell the truth to his own father, I’m going to walk home now and contemplate where I have gone wrong all these years”.
“But Dad, its 18 miles to home. It’s dark. You can’t walk home.”
My protests, my apologies and the rest of my utterances were useless. I had let my father down, and I was about to learn one of the most painful lessons of my life. Dad began walking along the dusty roads. I quickly jumped in the car and followed behind, hoping he would relent. I pleaded all the way, telling him how sorry I was, but he simply ignored me, continuing on silently, thoughtfully and painfully. For 18 miles I drove behind him, averaging about five miles per hour.
Seeing my father in so much physical and emotional pain was the most distressing and painful experience that I have ever faced. However, it was also the most successful lesson. I have never lied to him since.

Составьте текст на 15-20 предложений по тексту "A.A. Milne". Самое главное. Срочно, пожалуйста! На английском


Alan Alexander Milne was born in London on January 18th, 1882. His father was the headmaster of a small preparatory school. One of the teachers at the school was the famous writer H. G. Wells.

Milne, the youngest of the family's three sons, went to Westminster School at the age of 11 and then went on to Cambridge to become a mathematician. But he never did. Instead he became editor of the university's journal "Granta" in which he published some of his light humorous poems. Then he went to London hoping to earn his living as a writer. By and by London magazines began to publish his witty works, and in 1905 he published his first book, a shilling paperback collection of humorous essays. Aged only 24 he was given a post of assistant editor of the famous magazine "Punch", at the salary of 5 pounds a week - a lot of money at that time.

In 1913 he married Dorothy De Selincourt (Daphne to her friends) and the following year, when the war broke out, he joined the Army. At the front line he got ill and had to return home, to London.

The Milnes' only child was born on August 21st, 1920. Mrs Milne had hoped for a girl, to be called Rosemary ... instead she presented her husband with a lovely, fair-haired and adorable son, Christopher Robin. The Milnes bought him a teddy bear for his first birthday. The teddy bear was soon named Winnie, after a real-life bear that lived at London Zoo.

A. A. Milne wrote a lot of poems for Christopher Robin and about him. Some of the poems became very popular songs.

One rainy summer Milne rented a house in the country. He took with him a pencil and an exercise book, and in eleven days wrote so many children's poems that they filled a book. It was published in 1924 under the name "When We Were Very Young" and sold half a million copies!



In 1925 the Milnes bought a farm in Sussex, which they used for weekends away from London. From this old house it was a short walk over a bridge into the Ashdown Forest where Christopher Robin and his teddy, now known by the name of Winnie-the-Pooh or Pooh-bear, used to play. Each daily adventure in the Forest gave A. A. Milne more material for his now famous book "Winnie-the-Pooh" published in 1926. The illustrations to it were done by Ernest Shepard, who visited the Milne family in their farmhouse and drew quite a few sketches of Christopher Robin with his bear, the bridge nearby where the two played "Poohsticks", and all the well-loved Pooh characters and places.

A. A. Milne's secret for success was that he could get inside the mind of a child. He used his story-telling talents to describe how one little boy so loved his teddy bear that - for him at least - the toy animal came alive. After the book "Winnie-the-Pooh" A. A. Milne wrote another books of children's verses - "Now We Are Six" and "The House at Pooh Corner" which sold to a waiting public in millions of copies. The four Pooh books and Milne's enjoyable play "Toad of Toad Hall" are still as popular today as they were many years ago when they were written.

Christopher Milne (he no longer uses the name Robin) spent six years in the army during the war. Then he ran a bookshop in Dartmouth until he retired to live in the countryside.

What happened to Winnie-the-Pooh? Well, the bear was put into a glass case with all the other toy animals like Eeyore the donkey and little Piglet, at the Milnes' house in London when Christopher went off to school in 1930. Then, when the war came, the toys were 'evacuated' to America. Now they belong to some American publishing houses.
