You don't really believe that it's what you think it is: A zombie apocalypse. So you turn up the TV and wait for more information.
A new news reporter comes on the screen. He talks about what is going on. Good, you found what you need.
"This is not a drill. This is a zombie apocalypse. Residents are to not leave their homes. Stay inside and lock your doors."
Okay, so after that information, you should do stockpile up on things.
