Biased Grandparents

Grandfather Zhai and Grandmother Zhai were surprised to see their son coming home with a huge smile on his face. They both were having tea while enjoying the company of each other in this old age when their son came to disturb them. 

"How did you think of visiting your old parents?" questioned Grandfather Zhai sternly. He didn't show a good face to his only son. All his gentleness and patience were reserved for his wife and their dear grandson. As for this son, huh! It was already a miracle that he had never beaten him up. "And what's with that ugly smile? Put it away already! Don't scare the kids."

Zhai Kuijun's smile stiffened when he heard his father's comment but he chose to ignore it today. It didn't matter. He could definitely take this much. It wasn't the first time his father was so disdainful toward him. "Father, where are the kids? There are no kids who will be scared of my smile."

"But my old heart can't take it either," retorted Grandfather Zhai.
