We used to share everything—secrets, snacks, and even our dreams. But everything changed when we planned the school art festival together. I was in charge of drawing the poster, and Lily was responsible for collecting materials. I worked hard on the poster for three days, but when I showed it to her, she said it looked too dark and suggested changing the main colors. I got angry immediately. I thought she didn't understand my effort and didn't respect my ideas. "You never care about what I want!" I shouted at her and walked away without listening to her explanation. For the next week, I felt lonely and upset. The classroom, which was once full of our laughter, felt empty. I missed her company when I studied and her comfort when I felt sad. Then my mother noticed my bad mood and talked to me. She said, "Growing up means learning to put yourself in others' shoes. Lily might have good reasons for her suggestion." Her words made me think a lot. I realized I was too proud and didn't try to understand Lily. So I decided to apologize to her. The next day, I walked to Lily's seat and said, "I'm sorry for my rude words. Can we work together again?" Lily smiled and nodded. She told me she suggested changing the colors because she wanted the poster to attract more students. In the end, our poster won the first prize in the art festival.
