The evidence

Carl Black entered the ward with a big basket of fruits and when he saw Lisa, he greeted her with a smile "Hey."

Lisa's eyes wide opened with her mouth agape to see this and asked in surprise "Mr. Black why did you bring so many fruits?"

"What? This is for uncle, not for you."

"Very funny." She pouted and looked away from him.

Carl Black chuckled and shook his head. He sat down beside her and asked "Did Dr. Valentine visit today? What did he say?"

"Yes, he came. He said Dad is fit for tomorrow's procedure."

"Hmm," Carl Black nodded and continued "Did he say anything else?"

"No."

"OK."

After a few moments of pause, she started saying "I have to go to meet Anna in the afternoon. You please stay here."

He looked at her and said, "I'll drop you."

"No need. You stay here with Mom and Dad. If the doctor visits and says something else, Mom will get panicked."
