George Armstrong did not speak.
Beatrice Sabir took the watermelon to the kitchen.
"Aunt, I'm going to the bathroom," said Isla Astir.
Beatrice Sabir nodded, "Go ahead."
When Beatrice Sabir finished cutting the watermelon and came out of the kitchen, Isla was still in the bathroom.
Beatrice Sabir turned to look at the bathroom and said to George Armstrong in a low voice, "Can't you be more friendly to Isla? Try to chat with her. She's our guest! How could you be so obsessed with your books?"
The last thing George Armstrong wanted was to be disturbed while reading his books. "Our thought processes are not on the same level," he said, implying there wasn't much to talk about.
He was an undergraduate at a key university of "Project 985" and intended to continue his studies for a master's and doctorate.
What about Isla?
She studied at a normal university in Capital City, nothing special.
They live in different galaxies, unable to comprehend each other's experiences.
