Zombies and Danger Word

Zombies are the soulless, brain-eating creatures that we all know and see in movies and such. I never gave it much thought until today. I did not know that they originated from Haitian Voodoo. They were pretty much not dead people, but people that had their souls removed from them so that they will serve their master at all cost. It is practically like a servant that has no opinion and does everything that their master commands them to do. It is nothing like zombies that drool everywhere and go after human flesh. I wonder how it evolved from a brainless servant to flesh eaters?

In the story, the Danger Word, the one question that bugs me is that how is Grandpa Joe so prepared compared to the others. One cannot expect something like the appearance of zombies to be real at all. Even just now, people do say that the zombie apocalypse will happen and such, but it still is on the back of everyone’s mind. Pretty much no one takes it seriously at all. The most that everyone’s prepared from is a natural disaster like an earthquake or tsunami. I am curious of what happened to Grandpa Joe after he utters the ‘danger word’ at the end. Does he somehow turn into ‘one of them’ and go after the kid, or does everything end up in a happy ending? Sometimes I just end annoyed at endings that does not really give a clue on what would happen next or so… but then again, a lot of stories do that.
