Article: The first Ml choir rehearsal of the school year took place in the school hall. All the students joined together to sing. I watched as my elder sister and her grade came in and took their places next to us on the stage. Meanwhile, I could hear laughing. Some students were pointing at a girl standing next to my sister. I'd never seen this girl before. A girl whispered in my ear, " Did you know she's wearing diapers ?" After school that evening, I asked my sister about the girl I'd seen. She told me her name was Theresa and that she was a very nice girL ." Why were those kids being mean to her? I asked, "Because they're stupid," she said. One day, I was walking home from school when I heard voices behind me. "There's the little idiot's sister. Does your sister wet her pants too?" I walked a little faster and then I felt a atone hit me in the back. When I got home, I ran down to my sister's room. I pushed my way into her room, screaming at her. "Why do you have to be that giri's friend? I don't see anyone else being nice to her, " Janelle yelled back, Because she is a wonderful person and she is dying!" I will remember those words as long as I live. Theresa wet her pants because she had an illness, which was killing her. My sister was the only one nice enough to be her friend and stick up for her. A few months later, Hieresa passed away. I felt proud that Janelle was my sister. Throughout the years I watched her, and she always made friends with everyone. It didn't matter if they ware fat, thin, brilliant or not. She never left anyone feeling isolated or alone. It was she who changed me and taught me to never look at anyone in the same way again.

Article: Men and women have different tastes in food, with men favoring meat and poultry , and women fruits and vegetables, researchers said in what was said to be the most extensive study so far of gender differences in eating habits. More than 14,000 adult men and women, were surveyed from May 2006 to April 2007, for the Foodbome Disease Active Surveillance Network (FoodNet), to determine their eating habits, including high risk foods such as undercooked meat and eggs. "To our knowledge, there have been studies in the literature on gender differences in eating habits, but nothing this extensive," the epidemiologist told the 2008 International Conference on Infectious Diseases in Atlanta, Georgia. Researchers found that men were more likely to eat meat and poultry, especially duck, _ , and ham, and certain shellfish such as shrimp and oysters. Women instead were more likely to eat vegetables, especially carrots and tomatoes, and fruits, especially strawberries, blueberries, raspberries and apples. Women also preferred dry foods, such as almonds and walnuts, and were more likely to consume eggs and yogurt when compared with men. There were also some exceptions to the eating trends of each gender: men were significantly more likely to eat asparagus and brussels sprouts than women, while women were more likely to consume fresh hamburgers as opposed to the frozen kind, which the men preferred. And regarding high risk foods, the researchers found that significantly more men consumed undercooked meat and eggs than women, while more women were more likely to eat alfalfa sprouts. Men's preference for meat explains why men have more cases than women when it comes to high cholesterol , the study said.
