I'm a Bookworm Bully

My name's Mia, and I'll admit it, I make fun of kids who aren't as into books as me. It started last year when I mocked someone for preferring sports to reading during class book presentations. Now, I feel like this is my way of showing how smart I am compared to others. But lately, I've been wondering if maybe being so mean about it isn't actually that cool after all. What do you guys think, is it normal to put others down just because they don't share your passions? Am I really okay with what I'm doing?
