Yes kids “need” both parents at home. And, supposedly, they need to be of different genders too. The truth is that many kids grow up without a dad and turn out perfectly fine, meaning that a dad is not altogether necessary, though, I am sure, it is convenient to have one handy. One important lesson to learn in life is that after a certain point, neither parent is as necessary as they like to think, except, of course, for providing things like food and shelter.
Not being a daddy’s boy
Yes, that peculiarly obnoxious male sub-set. Guys who live to please their fathers. If you never had a dad it looks slightly gross, the fawning and submission and desperation for approval. The desire to imitate and to be servile. It’s a sign of all kinds of insecurities and and self-doubt, as well as an asshole father who plays emotional games with his children. Daddy’s boys are usually made that way by their fathers. It can be done with the right kind of manipulation.
None of the daddy issues that come from having a guy that looked like you in the house
The constant battles for control, the war between the young bull and the old one, the battle for attention from the mother. In the case of teenagers, there is the fact of being essentially a man and still being dependent for most of the essentials. The need to surpass and outdo your father in order to feel like a man, to compete and win, to be a better father, more successful etc.. All of these things plague guys with a live-in dad and at various turning points later in life.
No bad example
Every parent makes mistakes, is deeply flawed in ways that they can’t help but pass on to their children. This goes for everybody, no exceptions. One less parent is one less set of mistakes.
None of that paternal certainty that older men get
People like examples, younger men especially, although many men never grow out of it. It’s part of why sports are popular even among middle-aged men, they are all looking for people to admire. Role models. The role model, or template, makes you more certain that certain behaviors that you share are right. You get reinforcement. If you reflect the opinions and habits of your father you are more sure of them, even when they are wrong.There is less of the continual work-in-progress self-doubt that single-parent children have. They get set in their ways and never change because daddy was that way too.
