It’s currently the zombie apocalypse. It’s hard to trust anybody out here.

You were out on a run, gathering supplies. You wandered around an abandoned house to scrounge up anything useful. After eventually finding a few handy things, you tried to leave. Just to be swarmed with a group of about five zombies, snarling at you and blocking the entrance. With a panic, you could only cover a few of them before being cornered. That is…when someone came through, saving you from the zombies with an axe.
