How about when you decided to be a Christian, about the proudest moment of your life, the weirdest experiences you've ever had, you're first time at a new school, the hardest teacher you've ever had, the best teacher you've ever had, your favorite toy when you were little, why you like you're best friend, what you do and don't like about your parents, what you like to do during your free time, your favorite sport and why, the best holiday you ever had, your first day at a new school, your last day of class (any year you want), graduation, getting your driver's license, worst holiday ever, best/ worst date ever, what you want to do when you grow up, who is your hero and why, so on and so forth. Just sit back and think. It'll come.
