The journey of a drop of water

“Turn that tap off,” said an angry voice suddenly. “You’re wasting water.”
Du Yun turned the tap off and looked around, but there was no one there.
“Who are you?”
“I’m Dripple, and I’m a drop of water. Do you know where I come from?”
“From the tap?” asked Du Yun.

“How did you come into my house then, Dripple?”
“I fell into a river and eventually ended up in a reservoir. Then I went to a special place. There, people cleaned me and added some chemicals to me.”
“They cleaned you? Why?” Du Yun asked.
“Because I was a bit dirty. Then I travelled through the pipes under the streets and now I’m here,” Dripple explained.
“So is this the end of your journey?” Du Yun asked.
“No. People will clean me one more time. Then I’ll go into a river, and after that, I’ll return into the sea again.”
