Fathers not only influence who we are inside but how we have relationships with people as we grow. The way a father treats his child will influence what he or she looks for in other people. Friends, lovers, and spouses will all be chosen based on how the child perceived the meaning of the relationship with his or her father. The patterns a father sets in the relationships with his children will dictate how his children relate with other people. This theme awakens special interest because of the modification of the modern family structure, in which an increasing absence of fathers is observed. The main developmental theories are based on the conventional family model and it is possible that the new family configurations have repercussions for interpersonal and intrapsychic relations, making this theme relevant. The book looks at the effects on children with no father residing with them, and on children who did not know who their fathers were. It also encourages men to be father figures to the children of friends or family members, who may not have a strong male role model in their lives. Mentoring your children is one of the best things you can do.
