A scary-looking zombie leapt at me, trying to bite my shoulder. I dodged just in time. Then another attacked. I cried for help and three humans came to my rescue: a former student who has all kinds of zombie-fighting experience, a friend who lives on the other side of the continent, and the other, a person I know only in virtual reality. The battle was a blur, but thanks my rescuers, I survived to see another day.
