"Honestly, Petunia, why can't you just be happy for me?"

"For what?"

"I don't know; maybe because I just got engaged to the man I love? We're going to be married Tuney!"

"Why should I be happy about that?"

She kept turning the conversation round in her head. Why should she be happy? No matter what she did – how hard she tried – she was never good enough.

She got decent grades? Lily's top of her class.

She got accepted onto a typing course in London – London – well, Lily's decided she's going to become an Auror.

She introduces her family to her fiancé and Lily brings home that freak who's so bloody fascinating.

So, no, she couldn't be happy, because no matter what she was reaching for, Lily always did better.
