Margot is at a school on Venus where the sun does not come out.
The students treat Margot badly because she is different than everyone else.
The children are waiting for the sun to come out for the first time in seven years. They do not remember the sun because the last time it was out they were only two. They are all excited except Margot who is staying away from the window on her own. She is the only one who remembers the sun because she left earth at the age of four.
Right before the sun comes out the children lock Margot in a closet while the sun comes out and forget about her while they go outside and play.
Margot remains in the closet screaming and crying as she knows she is missing her chance to see the sun for the next seven years. The other children run and play outside like they never have before until thunder is heard and rain is felt.
As they return to the school one of the children remember Margot and the students walk silently to the closet to let Margot out. Now that the children have experienced the sun they realize what they did was horrible.
