27 Halli was seven when Ginny took her on her first trek to the North Pole. I actually saw some of the footage of that when Sarah showed it to me one day when we were together up in the Alps: a miniature hologram of Ginny and Halli leaning into the fierce wind, both of them on skis, harnesses around their waists so they could each pull a sled heaped with their supplies. I remember watching that and feeling so...inadequate. Like I’d never done anything interesting with my life, even in seventeen years, let alone in my first seven. But what Daniel said about it afterward made sense: that I didn’t grow up with someone like Ginny. I didn’t grow up with any of Halli’s early experiences. It wasn’t fair for me to compare myself to her, any more than it would be fair for her to feel inadequate
