Whenever I see a dad-daughter combination out in the wild, I’ll feel a little pang in my heart, in the same place where my dad-sadness resides. Even if I don’t know anything about the dads or the daughters, I feel compelled to cheer them on—like when you’re running down a hill and someone else passes you in the opposite direction. No matter how good an athlete they are, there is still a hill ahead for them to climb.
