Hi, my name is Drew, i am eight years old, and here is more about me. My favorite hobbies are solving mysteries and riding my bike, my favorite sport is basketball, my favorite subject in school is science because we get to do lots of fun experiments, and my favorite book series are The Hardy Boys and Ripley`s Believe It Or Not.
