If I could cast a patronus, I believe that mine would be in the form of a ladybug (or ladybugs, considering how small they are). Since the patronus charm is conjured based on one of your happiest memories, the ladybug suits me since one of my happiest memories is taking walks with my grandpa after he came home from work. On the last walk we ever took together, I remember finding a tree with hundreds of ladybugs on it; I've never seen anything like it since then. Even today, ladybugs like my room in my house in particular and I can find them climbing on the walls, on the ceiling, and crawling across the blinds on my windows. Finding ladybugs are also supposed to bring good luck and seeing them always makes me smile. : ]
