A father is one of the most important, influential figures in a person’s life. They can be a potent source of confidence and warmth, pride and wisdom. Dads are role models for their children, and the way they behave and interact with others, and the advice they dispense to their kids, will frame the way the youngsters perceive and interact with the world. There is a lot riding on those fatherly shoulders. And unfortunately, as opposed to jobs like Zamboni driver or professor of medieval literature, there aren’t any qualifying tests or seminars one needs to pass before becoming a father. That’s why so many dads are bad at being dads, and that’s why terrible idioms like these are so common.
