The short story "All Summer in a Day" by Ray Bradbury explores themes of jealousy and regret. On the planet Venus, it rains constantly except for one hour every seven years when the sun comes out. Margot, a girl who used to live on Earth where it was sunny, is bullied by her classmates for remembering the sun. When the sun comes out, the jealous classmates lock Margot in a closet so she misses it. Later, filled with regret, they realize their cruel actions. The story shows how jealousy can lead people to hurt others and later feel remorse.
