Living Like Luna Lovegood
Luna Lovegood. I always related to Luna when I started watching HP as a kid. She was so weird and comfortably different I just really saw her as a role model but at the same time saw myself in her. If that makes any sense what so ever.

After watching the Half Blood-Prince my family said I should wear shoes to bed since I'm known for sleepwalking. XD
This just makes me smile. Luna Lovegood, Harry Potter | Dumbledore's Army
