Lack of sense of distance
Teachers are polite to students because they have a sense of distance. When teachers face children, they are often prone to emotional breakdown and can't help them calmly.
Lack of majesty
Students are naturally in awe of their teachers, so they always restrain their words and deeds in front of teachers, and they are always eager to show their best side in front of teachers, so that teachers can keep a good impression on themselves. But for their children, whether parents are teachers or not, they are parents first, and there is no need to deliberately show only the good side between parents and children.
The depth of love is the cutting of responsibility.
For teachers, a student who has failed for a long time will be very happy as long as he can pass the exam, and even reward his children with his own pocket. But for parents, even if they pass, they are poor students and cannot be encouraged and recognized. Because parents often have higher requirements and expectations for their children.
