Article: I've done many things that would make any parent proud. I've taken part in sports, community work and school events, but I am most proud to be a good big brother. I have to watch over four sisters and a brother, plus myself. That's quitea task, but one I feel I have gotten good at. My brother needs more attention than most siblings. When he was nine, he was hit by a pick-up truck on the way to the bus stop and lost use of the lower two-thirds of his body. He's been in a wheelchair for six years. My brother does many things, but sometimes he tries to do things he used to do but can't now. I' m always there with words of encouragement. I now watch my brother struggle to do as many things as he can within and beyond his limits. Should he fall, I will be the person to pick him up. I also watch as my younger sisters grow up into intelligent, beautiful young women. Whenever my brother or sisters need a helping hand or words of encouragement, I'm on the job. That's what I, the big brother, am for.
