-The Seven Virtues of Harry Potter-
Purity:
-Luna's Virtue-
She wasn't a prude, but she wanted to wait. And she did, her purity stayed till she married. Her new husband, Harry Potter, was pleasantly surprised.
Temperance:
-Hermione's Virtue-
She didn't need much, was clean and healthy. Her self-control rubbed off on others, and it was the reason why she became a medi-nurse. To help others gain control over their own health and lives.
Charity:
-Molly's Virtue-
Even though she and her family didn't have much, she always gave. She gave everything for his family and unofficially adopted some orphans, like Harry Potter, and Luna Lovegood.
She would always give, more then she had, that was what made Arthur Weasely love her so much.
Persistence:
-Ginny's Virtue-
One thing that could be said about her was that she didn't give up. When something needed to be done, she did it.
She wasn't that smart, and she knew it. But she wanted to be something, so she studied, all the time.
Now look at her, she's the Minister of Magic.
Patience:
-Snape's Virtue-
One may not think that Severus Snape had any Virtue, but he did. After all, a spy has to be patient.
He used his patience, not just in his sideline 'work.' But he also used it with certain students, because sometime he really felt like cursing them.
Of course in the end, his virtue didn't help.
Kindness:
-Neville's Virtue-
Even though he didn't have much, he always was willing to give people the shirt off his back to them.
His kindness gained him many admires, and eventually a wife in Ginny Weasely.
Humility:
-Harry's Virtue-
He was famous, and he knew it, but that didn't mean liked it he. He didn't want the fame that came with him being the Boy-Who-Lived. He tried to stay away from the lime-light.
He liked not being popular, so he left to go where he could be lost. America, where he could be a nobody, along with his wife Luna Lovegood.
