they can run or not, one inescapable truth about zombies since their introduction to pop culture has been that they are conclusively no longer human. They can’t speak. They can’t avoid danger. They can’t use tools. They can’t hide and wait until your back is turned. They can’t organize and design an effective plan of attack. They can’t conserve their energy. They can’t defend themselves. Translation? Make sure there are none hiding in your house and then just shut your doors and windows. That’s literally all you ever need to do.
