Is the following microstory from Muhammad Ali "showing" or "telling"? In high school I boasted weekly—if not daily—that one day I was going to be the heavyweight champion of the world. As part of my boxing training, I would run down Fourth Street in downtown Louisville, darting in and out of local shops, taking just enough time to tell them I was training for the Olympics and I was going to win a gold medal.

a. showing
b. telling
