A doctor friend told a story. One day, a mother and son came in. The son was driving a luxury car, dressed in a suit, while the grandmother looked very ordinary, with a face full of wrinkles.

As soon as they entered, the grandmother asked, "How much does it cost to get a mouthful of teeth here?"
The doctor said, "It varies, from over a thousand to more than ten thousand."
The grandmother said, "I want to get the cheapest one."
While the grandmother was speaking, the son kept his head down, playing with his phone, as if her matter had nothing to do with him.
But the doctor specifically asked the son, who didn't lift his head and simply said, "Just do as she says."
Next, they started the dental work. After paying, the grandmother took out a torn cloth wallet from her coat pocket, took out 1,500 yuan, and paid the full amount.
Originally, the doctor said a 500 yuan deposit was enough, but the grandmother insisted on paying the full amount.
Throughout the process, the son just stood beside, playing with his phone, never lifting his head.
When they left, a few of us discussed inside the room, saying that this son was too unfilial—driving such a nice car, dressing so decently, yet letting his mother get the cheapest teeth and not paying for it.
While we were talking, the door suddenly opened, and the son came back.
He told the doctor to give his mother the best teeth, and he would cover the difference, but to never tell the grandmother the truth.
After the son left, we all fell silent, probably feeling guilty for doubting his character. $LTC
