My son said it was a classmate's birthday, and I said, 10, I won't buy food and bring a big bag home. My son lost his temper. How can he criticize education?
If the child is under 10, let him vent his anger. Look, maybe you're really wrong. After listening, analyze with him and tell him the reasons why you agree or disagree, and he will compromise. If he is over 10 years old, let him not follow the crowd. It's not impossible, but it must be meaningful, not happy, that is, environmental protection and thrift.
