The Wolf and the Seven Little Kids, a fairytale

The Wolf and the Seven Little Kids is a fairy tale collected by the Brothers Grimm. A mother leaves her seven children at home while she ventures into the forest to find food. Before she leaves, she warns her young about the Big Bad Wolf who will try to sneak into the house and gobble them up. The wolf will pretend to be their mother and convince the kids to open the door. The young children will be able to recognize their true mother by her white feet and sweet voice. The mother leaves and the seven kids stay in the house. Before long, they hear a voice at the door that says "Let me in children, your mother has something for each and every one of you". His gruff voice betrays him and the kids do not let him in. A little while later, they hear another voice at the door: "Let me in children, your mother has something for each and every one of you". This time the voice is high and sweet like their mother's. They are about to let him in when the youngest kid looks under the crack in the door and notices the wolf's big, black feet. They refuse to open the door, and the wolf goes away again...
