LILY, age 7.
"LILY! LILLYYYY! I told you to not play in the flowerbeds anymore! Look what you've done! Managed to pull all my best petunias out!" Lily's mom scolded her as she picked Lily up and began to dust her off.
Lily just laughed, and said, "Mother wait! See what I can do!" She then proceeded to wave her hand over the dirt, and her mother watched in awe as her daughter raised brand new tiny petunia buds. "I only wanted to grow a pink one!" Lily said timidly, not knowing what her mother would do. "Pink's Tunia's favorite! And we didn't have any!" She continued, now entirely fearful at her mother's reaction, seeing as her face had drained of all color.
However, her mother, being the kind, patient and loving woman that she was, did not strike her or cause any harm unto Lily. She instead insisted upon calling Lily's father and sister out into the yard, and although not one of them understood how, they all watched in awe as Lily raised flower after flower after flower.
Lily felt wonderful, she felt loved and accepted by the people she cared for most, and her biggest fear - that her family would reject her, was put onto the back burner of her mind and the happy faces of her mother, father and sister played in her mind as she fell asleep.
And they did. Her family accepted her, her mother never stopped loving her, her father couldn't have been more proud, and her sister thought it was an amazing gift, all up until that fateful day that a tawny barn owl came flopping through their window during the breakfast of Lily's eleventh birthday that everything changed. Her sister Petunia, although she supported Lily at first, realized that things were never going to be the same between them ever again.
Lily was always showing off something new she figured out she could do, always impressing their parents in ways that Petunia never could, and she felt like she couldn't compare. How could one's parents be proud of her top marks when Lily was off figuring out how to make things change colors? How could she compete with a person who could make drawings move? (As she would find out, Lily was a very advanced witch at her age)
The answer was that Petunia couldn't. She couldn't compete, so she stopped trying. She began to be snarly and bitter towards Lily, and when her letter came from said tawny barn owl accepting her into Hogwarts School of Witchcraft and Wizardry, that was The End of their Relationship. Lily went off to school, and the rest, well, is her story.
