The most stressful part of being the father of daughters is that you become the paradigm of male-ness to them, whatever that may be. Think about it: for her formative years a father represents half the population of the planet. It’s humbling.
But all that pressure and stress goes out the window when she runs to hug you when you pick her up from school or waves to you from the stage at the school play. In those moments, you’re not 50% of the population. You’re the only one she has eyes for.
I have a son too and I love him dearly. But daughters are different. If you have any kind of heart, they change you. I am better because of my girls.
