Rio glanced at the small golem and replied in a calm voice.
"Your father has transformed into a higher state of life… We living beings first grow up from newborns, then become adults, and finally turn into 'energy' as our mortal coils start to wither away…"
The small golem couldn't comprehend the complex words that Rio threw at it out of nowhere.
Rio has never experienced what it's like to have parents, which leaves him lacking in many emotional aspects.
He doesn't know how to properly console someone and help them in times of sadness and stuff, as he never had anyone to console and care for his feelings either.
But he did see on the internet that you shouldn't be too straightforward in these kinds of matters.
When telling a child about their parent's death, it's better to hide the truth behind a wall of complex words that they will slowly comprehend themselves as they grow up.
