This section emphasizes the importance of exercising caution and prudence in relationships with others. One should avoid acting impulsively; first, it is essential to observe the person and evaluate the potential benefits or harms that their relationship might bring. These are effective criteria, almost always based on the principle of advantage/disadvantage or benefit/harm; however, note that it does not refer to economic or material gains, but rather to the possibility of complicating our lives or making them a little happier and more manageable, depending on the kind of people around us and the relationships we build.
