Khaled Hosseini said this quote

Though there had been moments of beauty in it Mariam knew that life for most part had been unkind to her.But as she walked the final twenty paces,she could not help but wish for more of it.She wished she could see Laila again , wished to hear the clangor of her laugh , to sit with her once more for a pot of chai and leftover halwa under a starlit sky. She mourned that she would never see Aziza grow up , would not see the beautiful young woman that she would oneday become ,would not get to paint her hands with henna and toss noqul candy at her wedding . She would never play with Aziza's children. She would have liked that very much , to be old and play with Aziza's children.Mariam wished for so much in those final moments. Yet as she closed her eyes , it was not regret any longer but a sensation of abundant peace that wshed over her. She thought of her entry into this world , the harami child of a lowly villager , an unintended thing , a pitiable , regrettable accident. A weed , And yet she was leaving the wolrd as a woman who had loved and been loved back.She was leaving it as a friend , a companion , a guardian.A mother. A person of consequence at last. No. It was no so bad , Mariam thought , that she should die this way. Not so bad.This was a legitimate end to a life of illegitimate beginnings. pg. 360
