"Why does the sun move across the sky?" A young Rome asked.
Greece looked down at the little boy and smiled. "It's Helios travelling in his chariot, of course!"
"Where does he go at night?"
"He goes to sleep and his sister takes her turn in the chariot."
"I see. If the sun and moon are brother and sister, I guess that means..." Rome smiled mischievously.
"Huh?"
"I am the sun to your moon."
"Silly boy. We are but human, we can't compare ourselves to the Gods."
"But we are immortal, aren't we?"
"Yes, we are."
"So you could say we are Gods, in flesh and blood bodies."
"You know, that way of thinking could get you in deep trouble in the future."
"I don't care. As long as I have you, everything will be fine."
Greece blushed. Despite being only a little boy, Rome was already as flirtatious as any grown man. She couldn't imagine what he would be like once he became an adult.
"Greece, why do we have light?" Rome asked, his innocent side taking over again.
"Without light, we wouldn't have day and there would be eternal darkness. Without it, we wouldn't have fire, which keeps us warm. Not only that, the crops that we rely on to survive, wouldn't be able to grow and we would all starve to death..."
"That would be terrible..." Rome interrupted. He yawned. "If light is so good, why do we need darkness?"
"Hmm, that's a hard one. I think you should give me some time to think about it. Maybe I'll tell you the answer tomorrow."
It's pretty hard to write something based on the prompt 'light'.
In my opinion, Rome would have thought of Ancient Greece as his older sister when he was a child, since so much of his culture was based off hers.
