He Wasn’t the Best Dad
Some people can’t take part in conversations about parental trauma. Everyone around them could talk about how emotionally or physically abusive their fathers were and how they’ve cut off all contact with them because they can’t forgive them.
Yet people like this guy wouldn’t be able to contribute. But a person doesn’t need to cause emotional or physical harm to be deemed a bad dad. Showing little to no interest in the life of your kids is enough to make you a lame father.
