They are also not their best.

They are the whole long complicated sum of themselves, and to love them at all is to keep the whole sum in view, even when they have given you every reason to reduce them to a single terrible line.

I kept the whole sum of my brother in view, through my fury, because I had known him too long and too well to do otherwise.

And it turned out to be the thing that let me help him find his way back to the better half of himself, which had never actually left, and was waiting, the whole time, under the shame, to be called home too.
