Jenny is my neighbor. She lives in a very old house. One day, I am playing outside and I see strange lights and smokes coming out of her house. I come closer to see what is going on. I hear that she is telling strange things. There are a lot of candles in the room. And then, I can't believe my eyes: an ugly frog suddenly changes into a man. That is when I discover that Jenny is a witch.
