“And when she at last came out, her eyes were dry. Her parents stared up from their silent breakfast at her. They both started to rise but she put a hand out, stopped them. ‘I can care for myself, please,’ and she set about getting some food. They watched her closely.
In point of fact, she had never looked as well. She had entered her room as just an impossibly lovely girl. The woman who emerged was a trifle thinner, a great deal wiser, and an ocean sadder. This one understood the nature of pain, and beneath the glory of her features, there was character, and a sure knowledge of suffering.
She was eighteen. She was the most beautiful woman in a hundred years. She didn’t seem to care.
‘You’re all right?’ her mother asked.
Buttercup sipped her cocoa. ‘Fine,’ she said.
‘You’re sure?’ her father wondered.
‘Yes,’ Buttercup replied. There was a very long pause. ‘But I must never love again.’

She never did.”
