Levity
Luna had finished her homework and wandered down to the Quidditch pitch. After she'd spent some time with Oliver Wood a few weeks before, she'd discovered that there were some really interesting magical creatures living there and whenever she was bored, she tended to come there to watch them for a while. That was if she wasn't with the Thestrals, of course.
When she reached the pitch and looked up, she was delighted to see Harry. Taking a seat, she looked up at him and watched him for a while, admiring his graceful moves on the broom.
She waited for a while, then cleared her throat. "Hi Harry!" she called, waving.
