A Secret

When Tang Shi Yi reached home in the evening, she found that the television was on, but Ye Heng and the twins were not paying attention to the TV program.

The three of them sat together while discussing something in a low voice.

Tang Shi Yi thought that their action was a bit suspicious, especially when they seemed to not notice her presence.

"Shi Yi, you're back."

Tang Shi Yi was about to sneak on them when her mother came out of the kitchen and greeted her.

Mother Tang's voice made the others look up.

Tang Shi Yi did not miss the shock on her daughter's face. However, the little girl composed herself very quickly and smiled. 

"Mommy!" Xiao Xiao jumped off the sofa and ran over to her mother. "When did you come back?"

"I saw that you were discussing something with your father and Elder Brother," Tang Shi Yi pointed out. "What were the three of you talking about?"
