Raghav was having a bath and as he usually does, was playing with the water and wasting quite a lot of it in the bargain. I immediately reminded him and recalled the documentary we had recently watched on conservation of resources.
He promptly said: "Amma! It is ok if we don't have water on Earth. Maybe by that time, all the other planets in the solar system will become like the Earth and we could go live there if we want to!"
Now what do I say to that? I really don't know!
