| Once I went shopping on my first visit to Macao. 1 from cold and cloudy England, I enjoyed the sun and dressed in a T-shirt and a 2 skirt. Not having much 3 to enjoy the sun in England, my legs were very white. In England this is not a fashionable (时髦的) look at 4 . Most women spend every 5 day out trying to get darker skin. The darker the skin, the better the look. I have tried to get darker but 6 works for me! As I 7 around one shop the two shop assistants kept looking at my legs the whole 8 , talking quietly to each other in Chinese. I began to feel 9 and asked my friend if we could leave. After we left the shop, she asked me what was 10 . I complained about the shop assistants being very 11 . They must be talking about my white skin. My friend laughed." They weren't laughing at you. They were saying how 12 your legs are. Many Chinese women want to have white skin like yours. 13 , there are many beauty products (美容产品) in the shops to make skin whiter and a lot of money is spent on them." It just shows that we are never 14 with what we have. The grass is always greener on the other side. If the women of the West and East 15 the same way, Western women wouldn't spend so much money on cream that makes skin darker and women from the East wouldn't need to use cream that makes skin whiter. | ||||
