The Three of them were beautiful, in the way all girls of that age are beautiful. It can't be helped, that sort of beauty, nor can it be conserved; it's a freshness, a plumpness of the cells, that's unearned and temporary, and that nothing can replicate. None of them was satisfied with it, however; already they were making attempts to alter themselves into some impossible, imaginary mould, plucking and pencilling away at their faces. I didn't blame them, having done the same once myself.

Somebody has been a complete ratbag all their life and they've gotten away with it, and they die happy and rich, we so much want to believe that they're going off to the halls of judgment, that their heart will be weighed against the feather of truth, that it will be heavy with sin and it will be eaten by a crocodile. It's almost essential to our well-being to have a fallback position like that. It may appear as if you've gotten away with it, but you'll pay for it later.

Those who live alone slide into the habit of vertical eating: why bother with the niceties when there's no one to share or censure? But laxity in one area may lead to derangement in all.

She knows the rituals, she knows how we're supposed to be behaving...But I think these things are impenetrable and fraudulent, and I can't do them without feeling I'm acting.
