Final answer:
After Margot is released from the closet in the story 'All Summer in a Day,' the children feel guilty for having mistreated her.
Step-by-step explanation:
The question refers to a story where children lock Margot in a closet, and you’re asking how the children feel after Margot is released from the closet. While the provided text does not directly come from the story “All Summer in a Day” by Ray Bradbury, in which this situation occurs, it does highlight themes of guilt and regret. Hence, if we're referring to that story, after Margot is released from the closet, the children feel guilty. They are ashamed of their actions when they see how their selfishness has caused Margot to miss the rare event of the sun coming out on the perpetually rainy planet of Venus, something she had been eagerly looking forward to since she was the only one who remembered the sun from her past life on Earth.
