Little Red Riding Hood

One crisp autumn day her mother made a rich moist fruit cake, and said to Little Red Riding Hood, although she herself sounded quite bad, "My beautiful little red-hooded delight, I have sad news. Your grandmother is feeling sick. Please don't cry, it makes your cheeks blotchy. Be so kind as to take her this cake and this bowl of rum butter, so she can get better. And do not forget the most important thing!" What great advice was her mother about to give the girl? Was it something about safety?

"Don't forget to wear that precious red cape
I made for you!"
