First of all, talk about material things. Tuition alone costs a lot of money every year, including six years in primary school, three years in junior high school, three years in senior high school and four years in college. It costs money every year. It's okay for children to live at home, just paying tuition, but after they go to high school or college and leave home, they need to prepare a lot of accommodation and pocket money, including the usual ones. Parents need to worry, so material things are more difficult, which is why we see a lot of news that some children don't go to their favorite universities because of their family financial situation.
In addition to these, children will actually encounter many problems when they grow up. If they want to grow up healthily, we should always observe their psychological changes and give them some guidance. But for parents of ordinary families, these parents are busy with work every day and have little time to spend with their children. Therefore, in order to make children grow up better, they can only sacrifice their rest time to communicate with their children, but there are many contradictions during this period, so for parents.
If you were born in a very ordinary family, but you have successfully gone to college or graduated from college, then you must thank your parents well, because your parents have paid too much for your successful going to college. Maybe there is any contradiction between you and your parents, but there is no denying that your parents must be the people who love you the most in the world, because they are willing to pay selflessly for you.
