On the day when my sister was admitted to the undergraduate program, my parents booked a room at the hotel where I worked. She was wearing a princess dress and a crown and was surrounded by stars. I was wearing a dirty apron and walking among the crowd. The child laughed shrilly and sang children's songs, saying that I was an ugly duckling and my sister was a white swan. My parents lost face in front of the guests, suppressed their anger and pushed me out. "Did you do it on purpose? You were just jealous of your sister and deliberately ruined her college entrance party!" At that moment, I calmly took off my apron and threw it on the ground. "Yes, I'm just jealous of her."
