I'm a kid. Helpless, and delicious to wolves. Wont you help keep me from being eaten by one?
Don't hurt me, sir! I'm just a little boy! What are you doing out at this time.  Where are your parents? My parents are working in the kitchen, but I got bored and thought I would explore the castle tower. I must escort you back at once.  You are going to be in big trouble young man. Please, don't tell my parents! They're going to be so mad! QUIET this way at once! You hit me! I'm just a child, you monster! One more word from you and I'll take you to the king myself.  You don't want him to get a hold of you! Let me go at once! I know how to use a sword! Don't make me kill you myself.  You think being a child will save you?  You've committed crimes against the kingdom.  It's time to die. Please, I was only joking! I haven't hurt anyone!  Silly child! to think you would throw your life away over something so silly.  It's all over
