помогите перевести пжл!!

"Let me tell you a little about myself first," said Happy Bapetsi. "I come from Maun, you see, right up on the Okavango. My mother had a small shop and I lived with her in the house at the back. We had lots of chickens and we were very happy.

"My mother told me that my daddy had left a long time ago, when I was still a little baby. He had gone off to work in Bula- wayo and he had never come back. Somebody had written to us - another Motswana living there - to say that he thought my daddy was dead, but he wasn't sure. He said that he had gone to see somebody at Mpilo Hospital one day and as he was walking along the corridor he saw them wheeling somebody out on a stretcher and that the dead person looked remarkably like my daddy. But he couldn't be certain.

"So we decided that he was probably dead, but my mother did not mind a great deal because she had never really liked him very much. And, of course, I couldn't even remember him, so it did not make much difference to me.

"I went to school in Maun at a place run by some Catholic missionaries. One of them discovered that I could do arithmetic rather well and he spent a long time helping me. He said that he had never met a girl who could count so well.

"I suppose it was very odd. I could see a group of figures and I would just remember it. Then I would find that I had added the figures in my head, even without thinking about it. It just came very easily. I didn't have to work at it at all.

"I did very well in my exams and at the end of the day I went off to Gaborone and learned how to be a book-keeper. Again it was very simple for me; I could look at a whole sheet of figures and understand it immediately. Then, the next day, I could remember every figure exactly and write them all down if I needed to.

"I got a job in the bank and I was given promotion after promotion. Now I am the No. 1 sub-accountant and I don't think I can go any further because the men are worried that I'll make them look stupid. But I don't mind. I get a very good pay and I can finish all my work by three in the afternoon, sometimes earlier. I go shopping after that. I have a nice house with four rooms and I am very happy. To have all that by the time you are thirty-eight is good enough, I think.

Mma Ramotswe smiled. "That is very interesting. You're

right. You've done well."

"I'm very lucky," said Happy Bapetsi. "But then this thing happened. My Daddy arrived at the house."
