In a bag
Wow, this conversation took a turn for the worst really quickly, we wondered what kind of movies this child has been watching. This four-year-old girl must really be into some horror films if she can think up some things like this. Either that or they have a demon in the house that is possessing her.
We have to admit that if we heard our four-year-old child saying something like this, we would call a priest into the home to speak with her. We need to make sure that no evil entity has corrupted her mind. Chopping heads off and sticking them in bags is a detailed image.
