Margot was the new girl from Earth coming to her new school on Venus.
Margot doesn't like it on Venus because it is always raining and the sun never shines like it did on Earth, and Margot gets made fun of because she talks about the sun.
Then Margot was telling her classmates about how the sun was going to shine of Venus for the first time in 7 years... of course none of the classmates believed her so they locked her in a closet at school.
While Margot was locked in the closet the sun actually shined on Venus, all the students stood in amazement there skin finally kissed by the warm sun with no rain, nothing but a blue beautiful sky.
After the sun shined on Venus for a few minutes it began to rain and become dark again and all the students were upset that the sun was gone, then they realized that Margot was still in the closet and she never even got to see the sun that she has been patiently waiting to see again.
All the students felt bad that they locked Margot in the closet, so she couldn't see the sun, that she won't get to see again for another 7 year. The students hesitantly went to unlock Margot out of the closet and apologize for being mean and not listening to her when she told them the sun was going to shine down on Venus.
