Im not a father yet.

Discipline, Hearing whats being said, rather than listening to their mother just nagging, being subjective, sets guidelines, Role Model, good provider, teacher, integrity, tough but fair, children feel protected (physically, psychologically), not afraid to own up to ones mistake, respect women, brave and not violating childs trust, responsible, self control and restraint and so on. Thats not to say the mother wouldnt bring many of them but some of them a man is so much better in than a woman.
