They quickly finish their dinner and started to discuss about the water use.
"Even if we all still have enough water, we really should reduce our water consumption,"
Dylan reminded the others.
Mark nodded. "For drinking, it'll be enough for the next month or two. But if we have to take a bath or others, it'll definitely not be enough."
"Can't we take the rain water?" Lucy asked.
"It's not impossible, but you can't use them directly because who knows what's contained within if you collect them after they fell on the roof, wall, or others. And it wouldn't be easy to get the clean water unless you're at the rooftop." Anna shook her head.
Lucy looked at Anna speechlessly. "At this kind of times, you sure can use your head well."
Anna: "…" I'm not stupid, thank you.
"How about toilet?" Lucy asked.
