Mrs. Mi
Mrs. Ha
Mrs. Mi is taking with her neighbor, Mrs. Ha.
What’s the matter, Mrs. Ha?
I’m worried about my most recent water bill. It’s enormous.
Let me see. 200,000 dong! You should reduce the amount of water your family uses.
How do I do that?
First of all, get a plumber to make sure there are no cracks in the pipes.
I’ll do that.
Baths use twice as much water as showers, so I suggest taking showers. And remember to turn off the faucets. A dripping faucet can waste 500 liters of water a month.
I see. Thank you
