    As a mother of three young girls, Alison Cowan worried about her daughters growing up too fast. From asking for the latest toy to wanting to wear make-up, it seemed to Alison and her husband. Alan, that their children were never satisfied with what they had.

    The girls would ask for a toy, but would lose interest in it as soon as their friends had something new. Birthday parties were no longer just a few party games and blowing up balloons. All the parents seemed to invite professional performers and compete over who could give the most expensive party bag. At just seven years old, Amy and her friends were paying more and more attention to their appearance. It was a feeling that many parents would have.

    However, few would dream of leaving a comfortable family life and a comfortable house to move their family 3. 000 miles away to Africa in search of a simpler life. But last June, Alison and her husband, Alan, moved with their daughters to Kampala in Uganda, to show them a different lifestyle.

    For almost a year, the girls play in the red, dusty streets with local children and visit markets to buy fresh fish and vegetables for dinner. They have been able to play and use their imagination away from the distractions(分心) of the consumer-driven society. Now, instead of competing over who has won a computer game, the girls think about things like the frequent water shortages and electricity cuts in certain areas. "At times, we've been without water for five days. The girls always accept it, though. Their world before had been so small, but now they understand 93."
