The Story That Little Red Riding Hood's Grandmother and the Big Bad Wolf Have to Tell

Why does Grandma still live there alone even though she knows there is a big bad wolf deep in the forest? Why did Little Red Riding Hood go home alone even though she knew it was getting late and it would be dangerous to go back alone? Why didn't Little Red Riding Hood go to the doctor when she knew her grandmother was ill in bed? Why did the big bad wolf swallow grandma in one gulp but was not hurt at all? The author doesn't know either, hahahahahahahahaha
