The storyteller's words are like a painter's colors. Changing just one word in a sentence can alter the picture or detail that a listener is imagining. For example, construct a sentence without any adjectives. Then more generous. Add some descriptive words and see how the picture evoked by the words changes. The more the storyteller says, the more the listener will "see" in their imagination.
A man walked down the road.
A tattered old man walked down the hot dusty road.
A young man walked down a crowded city road.
