"Someone once told me that to love is to be loved. I think that is a lie. To love is to be vulnerable."
Lana Weasley is enrolled into Hogwarts. While, for a lot of wizard kids, this would be the best day of their lives, for Lana, this could be the worst. Immediately, Lana is made fun of for being a Weasley. She is made fun of because she has red hair, because she wears hand-me-downs, because she's a little different.
But Lana is not the girl that is offended easily. It takes a lot to make her break, but this is the very reason that Lana feels vulnerable.
