Professor Sterling nodded. "That's right."
The girl pouted with a look of distaste. "I don't want to!"
"Why not?"
"Because Grandpa is always so busy. He doesn't have time to play with me and my sister, and it makes Grandma unhappy. So I don't want to be a medical scientist. I want to have lots of time to spend with my family."
Professor Sterling lowered his gaze slightly, an inextinguishable sorrow in his eyes. Then he smiled and said, "But being a medical scientist means you can save many lives, giving them more time to spend with their families."
"Grandpa, is that why you don't have time for us? Because you're trying to give more people time to spend with their families?"
Professor Sterling nodded. "Yes. Being a medical scientist is a very noble profession. You can help many people and make great contributions to the country. Grandpa hopes that my Joy can become that kind of person too—someone who contributes to society and humanity."
