A wise fish
Baby fish born and raised in the water are so transparent that they can't be seen.
He forgot about the invisible water and went on a trip to find it.
One day, fortunately, he met a wise fish and asked, "What is water?
Where can I get it?"
Then the wise fish circled around the place, leisurely and moved away.
*This question does not tolerate any thought-provoking answer.
If you open your mouth to answer, it's like dropping black ink on clear water to dirty the whole water.
But if the seeker is desperate, there is an answer in everything that is perfectly normal.
