I'm also from Australia and honestly? I'd freak out. Maybe it's just the fact I live in a rural town with a population around 100,000 but it's creepy enough being at the local "mall" around closing time. So yeah, I'd freak out, then probably have to raid the chemist for some Valium, call the cops to come get me out and in the meantime jump at every little sound. I'm not proud of the fact that I am a total wuss. I love reading about the zombie apocalypse but that's the end of my bravado lol.
