What would you do if you found that your daughter and a male classmate often send text messages and make phone calls?

The latter two are obviously absolutely impossible, which is equivalent to pushing children to their own opposites, and it is easier to spread the influence of things. . . The first method is feasible, but we should pay attention to the method and discretion, and try to be tactful and subtle. Of course, texting and calling may not tell everything. Parents should have confidence in their children and at least know how bad they can be. . . . It is no problem to take some appropriate preventive measures.
