“But I’ve been thinking about how the trunks of trees bend and curve when they grow next to each other. Their leaves twist to accommodate each other. Their closeness reads on the shape of them, and you can infer the shape of one from the shape of another. When you know someone and you grow together, your shape and form become theirs. And so even though Rob is gone, and there’ll never be another Rob, another friend I’ve known as well or as closely, the impression his life left on me will always be there, and in that sense we haven’t lost him at all.”
