I used to think that there was a giant green monster who spied on me every night through my bedroom window. He was about 50ft tall but since he only did it at night nobody knew about him but me. I thought that he was sent to eat me but never could bring himself to do it because he was so nice. Eventually he stopped coming to my window to eat me but just to learn more about me. I never looked out the window to see him though because he could have a change of heart.
