This was originally from Neville, but since I do not ship Nuna, I've changed it to Rolf. I'm much more like Hermione, so I find Luna hard to write because I have a bit more trouble relating to her. Anyway, hope you like it!
Dear Luna,
Luna Lovegood hummed a little tune to herself as she swept the floor of Magical Menagerie. She had been out of Hogwarts for five years, and had decided she wanted to work with animals until she had the money to go hunting for crumple horned snorkacks. Having attended her good friend Neville's wedding to Hannah Abott this past weekend, she was in quite a good mood. She added a little dance to her tune as she rounded the corner where the owl cages were.
"Oof! I'm so sorry miss, are you alright?"
Luna smiled dreamily up at the man she had bumped into, and accepted his hand to help her up.
"Oh, yes, I'm quite alright. I suspect the nargles got to me." She replied.
"I see. They can be quite troublesome." He replied, nodding seriously. Luna eyed him for a moment, trying to figure out if he was taking the mickey. "I'm Rolf, by the way. Rolf Scamander."
"Luna Lovegood."
"Oh! Is your father the editor of that delightful publication? The Quibbler?"
Luna nodded. He grinned in return.
"I've always found his articles intriguing. Would you like to have coffee with me sometime? I'd love to discuss his articles about the crumple horned snorkacks."
Luna agreed, and couldn't keep the dopey grin from forming on her face as the man left the shop. It was nice to be taken seriously every once in a while.
You had me at Nargles.
Love,
Rolf
