You call an eighteen-year-old boy a boy? In my country, these guys are already going to serve in the army. Where is childhood here? These are adults and already sexually mature people who must understand that upon reaching adulthood, a person bears full responsibility for each of their actions. The participation of a father or mother is not required at all. As for parental concern for the future, it should begin at birth and end when the boy becomes an adult. It is necessary to raise him so that he understands what is allowed and what is not, and what happens if a person breaks the law. Coddling adult children means losing yourself in their eyes, losing their respect, and contributing to the fact that you will solve every problem for your child until he gets old. If you love your children, let them become adults, solving their problems themselves.
