We're All Dead

There are six types of people in this world.
The type who grew up preparing for the event of a zombie apocalypse, waiting for it to happen.
The type who never ever thought anything could go wrong in the world. Everything was perfect.
The type who in the duration of a zombie apocalypse put all their efforts into survival.
The type who refuse to take action against the zombies in fear of becoming just as bad.
The type who will walk through a zombie apocalypse not caring what happens to them.
And the type who believes we're all dead.
