Fear of the unknown
Fathers tend to be the ones who push sons out of their comfort zones. While a mother’s instinct might be to coddle a child who is afraid to make new friends or try something new, a father is often the one to encourage kids to try something, even if they’re afraid. It starts with simple things, like encouraging kids to try sports they’ve never played before, or ride a bike without the training wheels. Those kids grow into adults who have a curiosity, rather than fear, of the unknown. Children who didn’t have that encouragement of curiosity from a father might grow into adults who struggle to leave their comfort zones.
