You've never heard tribute paid to a parent by someone you admired? Or do you think it's always ceremony?
I can assure that you that there are those whom you look up to, who in turn look up far higher to a mother or father. And there are people who write about life as a parent--and not just mawkish mess with a glossy cover, I mean that rare stuff of substance--who cause far more words to pour out than Ben has here, which is to say nothing against him but much in their favor.
One final note: maybe no one is remembered by name for their work as a parent or partner--not that it matters to most--but there are some who are known and remembered for how bad of one they were. And their legacies are tainted, no matter what else they did.
