I walked to the store. Nothing particularly new here. You might even ask, "So what?"
But what happens when you change the verb?
I limped to the store.
I danced to the store.
I flew to the store.
With each verb change, the story changes. The first change implies an injury, the second implies a mood, the third implies either a mood or a fantasy (unless the narrator is a bird).
"I walked to the store" is not a story, but the last three sentences nearly are. One word makes a difference.
