Just as Lauren was about to grab the glass of water, she saw a math exercise book on the table in the living room.
It was only then that she remembered the question she wanted to ask Susan Harding.
"Auntie, when did Ruby learn about math? She's so amazing! She's ranked first in our class."
To Lauren's surprise, Susan Harding shook her head.
"I don't know when my child learned it either. When the math teacher told me about it, I was also surprised."
"Huh?"
Lauren Torres could not help but ask.
"Ruby's math has already reached the level of junior and senior high school. She's so amazing. Auntie, you actually don't know?"
Susan Harding frowned and shook her head. "I don't know. Last year, she couldn't even do addition for a single digit. This year, she inexplicably stopped reading those storybooks and became much quieter."
Susan Harding sighed.
