What I understood was that there was no keeping anyone safe—one person remembers to tip the nose up for the landing while the other person forgets to latch the door—and, in the end, it probably won’t be the nose tip or the door. It will be something infinitely more mundane. It will be life and time, the things that come for us all. Which doesn’t mean I’ll be able to keep myself from saying, Careful, call me, come right back. I will always be reaching for his hand.
