Just in case you don’t know the story ……..
A good king and queen live in a beautiful castle in a forest. The queen longs for a child of her own, but sadly appears to be unable to have one. Along comes a fairy Godmother who grants the queen a wish to have a child, and the beautiful Snow White is born. Unfortunately, one day when out in the forest playing with the animals, she becomes lost, and after a very long time, finds another castle.
Hoping for some help she goes into the dark, scary castle, she happens upon a magic mirror, which could see many things before it was covered in poisonous paint by the evil queen, but now sadly has no memory, and is only able to comment on what it can see at present. The mirror cannot lie.
Snow White cleans the mirror, which restores its memory. Upon being cleaned, the mirror remembers the past, and, seeing her beauty, warns Snow White to flee to avoid the evil queen.
When the queen returns, the mirror is forced to tell her about the beautiful girl, and admits she is far more beautiful than the queen, which sends the queen into a rage. The evil queen tells a hunter to kill the girl. However, the hunter is a kind man, and is unable to kill the girl, instead presenting the evil queen with a pig’s heart instead.
