Q: Article: I stopped at a grocery store the other day because I was about to go on a long drive and I wanted to buy my favorite beverage for the trip. It wasn't the store I normally go to, just one I passed along the way. As I walked up to the entrance, I noticed a man and a boy who was about 10 or 12 years old standing at the front of the store. Customers walked past, as the man handed them half-sheets of white paper. I walked up to them with curiosity, wondering what cause they were representing. As I got closer, I saw that they had two carts starting to fill with groceries. I said hello and the man greeted me and handed me one of the pieces of paper, explaining that they were collecting donations for the local food pantry. On the paper was a simple list of food items: peanut butter, noodles, pasta sauce, canned fruits and vegetables. It also included a short story about the boy and his efforts to collect food donations since the age of 8. I was really touched that someone so young would be so interested in helping others. I told him it was an awesome idea and that he should be proud of himself. He smiled. Then, I went inside to get my drink. Unfortunately, the store didn't have it in stock. But, I wasn't upset, because by then I felt I had another mission. I went through the store, picking things from the list, then brought them back out to the boy and put them in the cart. I also gave the man the white sheet of paper back to reuse for another customer. They thanked me and offered me a treat (candy, I think) but I said to pass it on to someone else. As I walked back to my car, the boy's well-intentioned spirit stuck with me. How inspiring to encounter a young boy with a resolve to do good deeds, and the courage to act on it. It made my day!

Q: Article: It's not easy to find a person with the qualities it takes to be a hero. I didn't really understand the meaning of the word "hero" until my third year in the college. If you saw her, you wouldn't think she really looks the part, but she is stronger than Superman could ever be. Her name is Sandra Keierleber. I first met her at volleyball tryouts , but didn't notice anything special at first. As the week passed, however, she showed she had more heart than anyone. She stood out because she never gave up, no matter what. Sandra isn't the tallest or the fastest --- in fact, this was her first time playing volleyball and it showed--- but that didn't stop her. She was always the first to arrive and the last to leave. By the end of tryouts she had found a place in everyone's heart. When the name list for new members was put up, we all waited nervously as she checked. When she stood at the door and smiled happily, all we could do was cheer. After Sandra made the team, she worked even harder to improve her game. When she asked for help, we gladly taught her. She also became our fan, attending almost every school game and even joining us in the city games. We all like her, because she never thinks about doing things the easy way, or loses that smile. Because of her great efforts, she makes herself a true hero--- and my hero, too.
