Wait for Everything to Blow Over
Magners has the right idea. During a zombie apocalypse, there’s not much you can do to escape the brain-eating creatures you used to call friends, family, and neighbors. All you can do is sit at a pub, drink a pint, and wait for the whole thing to blow over.
Of course, that’s assuming you can side-step your way past the horde of zombies waiting outside your apartment building. Also, due to the recent pandemic, we’re 99% that if a virus that turned people into zombies were real, the virus would spread more quickly than anyone could imagine, even if there were a vaccine.
