My father is a cleaner with low salary and hard work. My classmates laughed at me. I feel inferior and even look down on my father's work. What should I do?

Once, a man did an experiment and parked a car in the street. There was something in the car, which was dusty for a week. Three months later, when the car stopped, it looked the same.

The man parked another car with a higher grade in its original position. The difference this time is that the experimenter smashed a crack in the window with a stone, and the glass didn't rot, and then the experimenter left. Three months later, I found the dusty car. The car body was smashed, the windows were all broken, and everything in the car was swept away.

Whether a car is cheap or not, when it is always clean and intact, passers-by will know that the owner cherishes the car and cyclists will be careful not to rub it.

Even if the car is high-end, when the window is cracked and dusty, pedestrians know that the owner of the car has thrown it away or doesn't care, and sometimes it will be destroyed when passing by. The owner doesn't care about this car anyway.

If you are that car, you look down on yourself and let yourself be smashed to the ground. Those passers-by can hurt you to pieces.
