Answer:
It is difficult to have an interesting conversation with adults.
Step-by-step explanation:
The narration created by Jean disqualifies the conversation of adults, displaying it as boring, uninteresting, without excitement and dull, through the eyes of Edward, who prefers to interact with children who are more interesting and lively.
With that, Jean says that it is difficult to have an interesting conversation with the adults. Probably because their lives are as boring and unenthusiastic as their conversation. Unlike children.
