Watch zombie movie. Don’t notice until too late as cat bumps against leg. Jump straight into air. Emit “kiai!” karate noise. Scare dickens out of cat in return. Gather Almond Joy, popcorn and soda (amulets known to fend off undead attacks.) Watch rest of movie while getting “nexercise” – that is, turn head continuously in case zombies creep up unnoticed.
We shall never know all the good that a simple smile can do.
