Explanation:
This main detail about the narrator and the supporting details in the passage shows that the family might be longing for the life they used to have before such as life at Terra before going to Mars. According to the narrator, his imaginations run wild while looking out of the window. Though little, compared to the others she might have imagined life in Terra.
