"It's that what we call 'love' is actually letting your identity identity fill in around the shape of the other person—you love someone by defining yourself against them. It says loss hurts because there's nothing holding that part of you in place anymore. But your outline still holds, and it keeps holding. The thing you shaped yourself into by loving them, you never stop being that. The marks are permanent, so the idea of the person you loved is permanent, too."
