When Gou Dan arrived at his maternal grandparent's home, he saw his grandparents and other family members already eating. Seeing that they were almost done eating, he strode towards them furiously.
As soon as he entered the living room, he asked angrily, "Why didn't you wait for me to eat?"
Hearing his arrogant words, his eldest uncle glanced at him and asked displeasedly, "Jiande, how can you speak to your elders in this tone? Where are your manners?"
After hearing what his uncle said, Gou Dan frowned and said, "I always talk like this at my home. Why can't I do it here?"
Putting down the bowl and the chopsticks in his hand, Gou Dan's maternal grandfather looked at him coldly and said, "In my family, we all eat at regular times and will not wait for you. If you are late, just wait until the next meal."
