In an isolated cave hidden by a massive boulder, there was a confined room.
The confined room was spacious, for it covered the whole cave, while the single candlelight drove twenty percent of the darkness.
The massive boulder obstructed airflow, making it difficult to breathe. Inside the confined space, the two people struggled for oxygen while the single candle provided minimal illumination.
The boulder snugly fit into the cave opening, leaving only a small gap for oxygen to enter.
The two people, both eight-year-old children, sat apart from each other on opposite sides of the candlelight, their shadows cast against the cave walls.
Strangely though, one of the shadows was still, even when the flame swayed, it was still, and the size never changed.
Compared to the other shadow, who was restless even though the owner was sitting idly.
They remained quiet to sustain the oxygen.
