…When she entered a room everyone would turn to look at her,  but she almost always ended the night alone, in the convent, watching a TV that she hadn't even bothered to have property tuned. She gave all her friends the impression that she was a woman to be envied, and she expended most of her energy in trying to behave in accordance with the image she had created of herself.

Because of that she had never had enough energy to be herself, a person who, like everyone else in the world, needed other people in order to be happy. But other people were so difficult.
They reacted in unpredictable ways, they surrounded themselves with defensive walls, they behaved just as she did, pretending they didn't care about anything. When someone more open to life appeared, they either rejected them outright or made them suffer, consigning them to being inferior, ingenuous.

She might have impressed a lot of people with her strength and determination, but where had it left her? In the void. Utterly alone…
