What is in front of us now is the critical moment.Immediately you have to give up your old tone, he is still under your discipline, but no longer your student, but your friend, a man, from now on, you have to treat him like an adult .Don't give up authority when prestige is needed most.Precisely at the time when he has just learned self-control and is most likely to fall into the trap of serious mistakes, it is not self-discipline that will make him a complete adult.I cannot renounce my rights at a time when mine are most important to his interest.
