Your question does not specify, but i can infer you are talking about <em>All Summer in a Day</em> where the author talks about a futuristic event where people are living in Venus.
The people moved to Venus because it has been raining for 7 years there. However, the people have forgotten how the sun is like.
Coincidentally, there is a girl named Margot who is different from the others because she remembers the sun.
Her classmates hated her because she was different and because she was always silent and was about to go back to Earth.
