Final answer:
The children left Cousin Eunice for a few reasons: she told them to find their grandmother, Father Joseph said she couldn't be a nun if they stayed, and the children were curious to meet their grandmother.
Step-by-step explanation:
The children left Cousin Eunice for several reasons:
Eunice told them to go find their grandmother: This is one of the reasons why the children left Cousin Eunice. Eunice instructed them to go find their grandmother, which suggests that their grandmother might need their assistance or that it was time for them to be reunited with her.
Father Joseph told them Cousin Eunice could not be a nun if they stayed: Another reason why the children left Cousin Eunice is that Father Joseph informed them that she couldn't become a nun if they remained with her. This implies that their presence was somehow hindering Cousin Eunice from pursuing her religious vocation.
The children wanted to find out what their grandmother was like: The third reason for the children leaving Cousin Eunice is their curiosity about their grandmother. They wanted to meet her and discover what she was like, suggesting a desire for a deeper connection with their family.
