In Washington, I was planting a seed.  Jace, my next door neighbor, said, "How does a seed grow?"

"I dig a hole.  I plant a seed in soil.  Seeds need soil, water, and sun," I said.

"Wouldn't that kill the plant?" asked Jace.

"No."

"Oh."

"Plants and seeds need sunshine, moisture from rainfall, and--" I started.

"So bo?" Jace interrupted.

"Stop rhyming with 'O'!" I complained.  "Now, where was I?"

"Clouds," Jace said.

"No!" I said.

"No, I want to know about clouds."

"Okay.  Clouds are water droplets.  It's getting foggy.  We should go inside.  Air."

And that's how the story ends.  The teacher wrote that I should "have an ending to a story, please."
