"Are people that cold in your time?" asked Julia.
"Cold?" Vassi repeated in bewilderment.
"Heartless?"
"Heartless? I hardly think so."
"I mean callous, without pity, without compassion."
"I've been very busy. I haven't thought about it."
"Do men and women marry in your time?"
"Yes, they do."
"Are you married?"
"No, you see, I'm not very—presentable. Besides, I have my research."
