October 14, 2018: Identical
Zain and Zeina were born on October 14, 4214. Zeina is a moment older than Zain, who followed his twin sister into the outside world. They spent every moment together, except for when they needed to be separated by gender in their later years. Zain and Zeina experienced the ways of the world together. Most people found it endearing to see such a strong bond between siblings. Yet there was something different about Zain and Zeina. They spoke different languages. Zain spoke Arintese after their mother and Zeina spoke Rubono after their father. Neither understood the words of the other. But they always knew what each other meant.
In old age, both Zain and Zeina wrote memoirs of their lives. It was only after their passing that translators translated their works into a common language. It turns out, they looked at the world in completely different ways, yet shared all the same experiences.
