“I’m listening to those guys talking.”

Lai Yiu-Fai: 
“From this far away?”

Lai Yiu-Fai: 
“You have really good hearing.”
-
Chang: 
“It’s a habit of mine. I had eye problems when I was little. I couldn’t see well, so I listened. My sight was corrected, but I never lost the habit of listening. Sometimes I think ears are more important. You see better with your ears. You can pretend to look happy, but your voice reveals the truth. If you listen closely, you understand.”

Lai Yiu-Fai: 
“Really?
-
Chang: 
“Just like your voice now shows you’re not happy.”
