The Echo That Answered Late
Wren stood at the edge of a deep canyon. She cupped her hands around her mouth. "Hello!" she shouted.
Nothing came back. Wren waited and waited. She picked up a stone and tossed it into the grass.
At last, a tiny voice floated up from the canyon. "Hello!" it said. It was Wren's own voice, but it was very slow.
Wren laughed. "You are a late echo!"
"I am sorry," said the echo. "I am old, and my legs are long. I have to run all the way around the rocks."
Wren had an idea. Each day, she said her hello early in the morning. Then she went to school. When she came home, the echo was always ready.
"Hello, Wren," it said, right on time.
