Because parents who have software are very strict with their children. What will happen in the future is basically planned. Every step is going according to plan. For the sake of their children's future, they will ask them to take the designed route more strictly. So it was mistaken for impoliteness.
In fact, there should be such a rude performance. Children may not understand when they are young. But when you grow up and achieve great success, you will understand these requirements of your parents.
Therefore, it is a very happy thing to have a heartless and farsighted parent.
