Severus sighed, but began his story. "When I was living in Spinner’s End with my parents, my parents and I were back then neighbours with the Evans family. That’s where I know Lily. We once were neighbours and friends back then. I was also the one, who told her that she was a witch. Lily’s parents accepted her, but Petunia did not. Due to her jealousy and spite, Petunia began to hate Lily for being a witch and wasn’t happy that she wasn’t one too. I remember that she once wrote to Albus, why she couldn’t go to Hogwarts." At this Narcissa was stunned. A muggle had managed to have contact with a wizard. But Severus continued with his story. "Well, Albus did tell her that she wasn’t able to go since she didn’t have any magic, but her sister did. Her spite and jealousy turned to hatred and loathing, because in her view, Lily got everything, what she didn’t get. The point is that Lily had inherited the good traits of her family, was academically gifted and had also magic. Petunia on the other side inherited the bad traits of her family and wasn’t really a bright head. She had also had a bad taste for spouse material. For example, when she got married. Against her parents’ exact wishes, she married Vernon Dursley. I can tell you, when I have seen the man, I thought that I wasn’t meeting a human, but a whale or a walrus. Dear Merlin was he overweight." Narcissa could see that Severus had rolled his eyes by the mention of Vernon Dursley, how the muggle looked like.
